Based on the previous research series on wormlike micelles, this paper focuses on the intelligent design mechanism, construction strategies, classification systems and practical applications of SWLMs. The intelligent response of micelles relies on reversible non-covalent weak interactions and adjustable dynamic equilibrium, and external stimuli can change the critical packing parameter to realize reversible morphology transformation between spherical and wormlike micelles, further achieving sol-gel transition and rheological regulation. There are two mainstream construction approaches: Functional modification of surfactant molecules and regulation by the responsive hydrotropes. This paper systematically summarizes six typical stimulus-responsive systems, including temperature, pH, light, redox, hydrocarbon, and multi-coupled response systems, and clarifies their microstructural evolution and macroscopic rheological response mechanisms. Among them, hydrocarbon-responsive micelles have achieved large-scale commercial application in oilfield clean fracturing fluid, while pH, photo and redox-responsive systems show great potential in drug delivery, microfluidic control and green cleaning fields. At present, single-stimulus systems have limited application scenarios, and multi-stimulus coupled wormlike micelles developed via dynamic covalent bonds are the mainstream research direction. This review paper compares the advantages and limitations of different construction paths, analyzes the existing technical bottlenecks such as poor long-term stability of surfactant-hydrotrope systems and incomplete response reversibility of partial photo-responsive systems, and provides theoretical reference for the targeted molecular design and industrial application of high-performance SWLMs materials. 数据和表 | 参考文献 | 相关文章 | 计量指标

The co-stabilized Pickering emulsion achieves an anthocyanin encapsulation efficiency of 98.5%. Under ultraviolet irradiation, the anthocyanin retention rate in the co-stabilized emulsion is 1.4 times, 3.3 times, and 36.9 times higher than that in the SiO2 NP-stabilized Pickering emulsion, Span 80-stabilized emulsion, and free anthocyanin solution, respectively. The co-stabilized Pickering emulsion also demonstrates excellent storage stability, with a minimal increase in droplet size of only 38.2 μm after 21 days of storage at 37 ℃, significantly lower than the increases of the SiO2 NP-stabilized Pickering emulsion （94.6 μm） and the Span 80-stabilized emulsion （263.3 μm）. These results indicate that the synergistic interaction between SiO2 NPs and Span 80 not only improves the stability of the Pickering emulsion but also enhances the photostability of anthocyanins. This study provides a promising platform for improving the stability of active ingredients in the daily chemical industry. 数据和表 | 参考文献 | 相关文章 | 计量指标

硫原子位点调控增强有机光热剂抗菌性能 Enhancing antibacterial efficacy of organic photothermal agents via site regulation of sulfur atom 秦涛, 黄鑫, 崔效源, 李芬芳, 杜意恩, 郝俊生 2026 (6):  717-728.  doi: 10.3969/j.issn.2097-2806.2026.06.003 摘要 ( 57 )   HTML ( 0 )   PDF(13481KB) ( 30 )   为探究硫原子精确位置对有机光热剂性能的影响，该文对比了两个具有给体-受体（D-A）结构的共轭小分子S-1和S-2，唯一的结构差异在于噻吩[3, 4-b]单元中单个硫原子的位置。理论计算结果表明，与S-1相比，S-2中硫原子的位置变化使其分子的二面角减小，分子平面度增高，HOMO-LUMO间隙减小（S-2为1.90 eV，S-1为2.10 eV）。光学表征显示，S-2在四氢呋喃中的最大吸收峰为770 nm，制备为纳米粒子（S-2 NPs）后红移至780 nm。光热性能测试中，S-2 NPs在808 nm激光照射下的光热转换效率为52%，高于S-1 NPs的44%。在抗菌实验中，在激光照射下，浓度为12 μmol/L时，S-2 NPs对金黄色葡萄球菌的杀菌率达99.1% （S-1 NPs为43.8%），15 μmol/L的S-2 NPs对大肠杆菌的杀菌率达99.9% （S-1 NPs为43.4%），20 μmol/L的S-2 NPs对白色念珠菌的杀菌率达96.0% （S-1 NPs为83.8%），并可有效清除金黄色葡萄球菌生物膜（40 μmol/L时存活率仅为16%）。细胞实验表明，S-2 NPs在40 μmol/L浓度下，L929细胞活力仍保持在80%以上。因此，S-2 NPs被认为是一种极具前景的光热剂。研究表明，对单个硫原子位置进行精准调控是一种提升有机光热剂光热转换效率和抗菌性能的有效策略。S-2 NPs具有优越的光热抗菌性能和良好的生物相容性，可以被加入到化妆品面霜、乳液或面膜中，以赋予光热抗菌功能，为延长产品保质期和增强皮肤健康提供种新的策略。 To elucidate the effect of precise sulfur-atom positioning on the performance of organic photothermal agents, this work compares two conjugated donor-acceptor （D-A） small molecules, S-1 and S-2, which differ only in the position of a single sulfur atom in the thiophene [3, 4-b] unit. Theoretical calculations revealed that compared to S-1, the altered sulfur atom position in S-2 reduced the dihedral angle, increased molecular planarity, and decreased the HOMO-LUMO gap （1.90 eV for S-2 and 2.10 eV for S-1）. Optical characterization showed that S-2 exhibited a maximum absorption peak at 770 nm in tetrahydrofuran, which was red-shifted to 780 nm when it was prepared as nanoparticles （S-2 NPs）. Photothermal performance tests demonstrated that S-2 NPs achieved a 52% photothermal conversion efficiency under 808 nm laser irradiation, surpassing the 44% of S-1 NPs. In antibacterial experiments, under laser irradiation, S-2 NPs at 12 μmol/L achieved a 99.1% bacterial killing rate against Staphylococcus aureus （43.8% for S-1 NPs）, 15 μmol/L S-2 NPs reached 99.9% against Escherichia coli （43.4% for S-1 NPs）, and 20 μmol/L S-2 NPs attained 96.0% against Candida albicans （83.8% for S-1 NPs）, effectively eliminating Staphylococcus aureus biofilms （survival rate was only 16% at 40 μmol/L）. Cell experiments indicated that S-2 NPs maintained over 80% L929 cell viability at 40 μmol/L. Thus, S-2 NPs are considered a highly promising photothermal agent. The study demonstrates that precise control over individual sulfur atom positions is an effective strategy for enhancing photothermal conversion efficiency and antibacterial performance in organic photothermal agents. With superior photothermal antibacterial properties and excellent biocompatibility, S-2 NPs can be incorporated into cosmetic face creams, lotions, or facial masks to impart photothermal antibacterial functionality, offering a novel strategy for extending product shelf life and improving skin health. 数据和表 | 参考文献 | 相关文章 | 计量指标

Ag3PO4/BiVO4/长余辉复合材料全天候光催化降解染料废水性能 Performance of Ag3PO4/BiVO4/long afterglow composite for all-weather photocatalytic degradation of dye wastewater 郭连霜, 杨玲 2026 (6):  729-738.  doi: 10.3969/j.issn.2097-2806.2026.06.004 摘要 ( 45 )   HTML ( 1 )   PDF(3306KB) ( 23 )   以长余辉材料Sr2MgSi2O7: （Eu2+, Dy3+），Ag3PO4和BiVO4等作为原料通过构建异质结的策略制备了一种具有全天候光催化活性的Ag3PO4/BiVO4/Sr2MgSi2O7: （Eu2+, Dy3+）（ABS）复合材料。通过SEM，XPS，UV-vis DRS，PL和EIS等表征手段对ABS复合材料进行了系统的表征。以亚甲基蓝（MB）染料溶液作为目标污染物，评价了ABS复合材料的全天候光催化活性和稳定性，提出了光照和黑暗环境中光催化的双Z型电荷转移机制。结果表明，模拟太阳光照射15 min，关闭光源黑暗环境继续反应15 min，Ag3PO4，BiVO4和Sr2MgSi2O7: （Eu2+, Dy3+）质量比为1∶1∶40的ABS复合材料对MB染料溶液的降解率达到了98.8%，循环使用5次后对MB染料溶液的降解率仍达到了98.5%，表现出良好的全天候光催化活性和稳定性。得益于Ag3PO4，BiVO4和Sr2MgSi2O7: （Eu2+, Dy3+）三者耦合后双Z型异质结的构建有效促进了光电子-空穴的分离，有效保留了Ag3PO4和BiVO4高氧化电位价带，光照条件下Sr2MgSi2O7: （Eu2+, Dy3+）通过缺陷能量填充积累能量，黑暗环境中释放能量激发Ag3PO4和BiVO4发生电荷分离，价带上高氧化活性空穴将H2O氧化为羟基自由基（·OH），在·OH和空穴的作用下实现了有机染料MB的高效降解。 The composites of Ag3PO4/BiVO4/Sr2MgSi2O7: （Eu2+, Dy3+） （ABS） with all-weather photocatalytic activity were prepared by constructing heterojunction using Sr2MgSi2O7: （Eu2+, Dy3+）, Ag3PO4 and BiVO4 as raw materials. These ABS composites were systematically characterized by SEM, XPS, UV-vis DRS, PL and EIS. Methylene blue （MB） dye solution was used as the target pollutant. The all-weather photocatalytic activity and stability of ABS composites were evaluated, and a dual Z-scheme charge transfer mechanism of photocatalysis in light and dark environments was proposed. The results showed that the degradation percentage of MB dye solution by ABS composite with the mass ratio of 1∶1∶40 reached 98.8% after 15 min of simulated sunlight irradiation and 15 min of continual reaction in dark environment. The degradation percentage of MB dye solution still reached 98.5% after 5 cycles, indicative of good all-weather photocatalytic activity and stability. Benefiting from the coupling of Ag3PO4, BiVO4 and Sr2MgSi2O7: （Eu2+, Dy3+）, the construction of dual Z-scheme heterojunction effectively promoted the separation of photoelectron-hole and effectively retained the high-oxidation-potential valence band of Ag3PO4 and BiVO4. Under light conditions, Sr2MgSi2O7: （Eu2+, Dy3+） accumulated energy by filling the defect energy. The energy released in the dark environment stimulated the charge separation of Ag3PO4 and BiVO4, and the high-oxidation-activity holes in the valence band could oxidize H2O to hydroxyl radicals （·OH）. Then efficient degradation of organic dye MB was achieved under the actions of ·OH and holes. 数据和表 | 参考文献 | 相关文章 | 计量指标

Then the surfactant was combined with KCl to develop a novel supramolecular clean fracturing fluid system which was suitable for deep coalbed methane wells. The comprehensive performance of the fracturing fluid system was evaluated in laboratory, and it was applied on site in deep coalbed methane wells. The results showed that this supramolecular clean fracturing fluid had strong temperature and salt resistance. When prepared with saline water with mineralization degree of 20×104 mg/L, after shearing at 120 ℃ with a shear rate of 170 s-1 for 120 minutes, the viscosity of the prepared fracturing fluid could be maintained above 50 mPa·s. The fracturing fluid system also had strong sand-carrying capacity, and when the experimental temperature was 90 ℃, the settling rate of ceramic particles was only 0.351 cm/min. This fracturing fluid had good gel breaking performance. When the volume fraction of kerosene was 10% and the gel-breaking temperature was 30 ℃ and 90 ℃, the gel-breaking time of the fracturing fluid could be shortened to within 60 minutes. All the performance parameters of the gel-breaking fluid met industry standards, and the damage of the gel-breaking fluid to the permeability of coal core was less than 10%, indicative of good reservoir protection effect. In addition, this supramolecular clean fracturing fluid had smaller impact on the desorption performance of coalbed methane than other conventional fracturing fluids. The on-site operational effect upon X-1 well using this supramolecular clean fracturing fluid was good. During the post-fracturing drainage stage, gas could be seen quickly. After 400 days of production, the daily gas production was basically stable at around 3 300 m3, and the effects of stable production and increased output were good. 数据和表 | 参考文献 | 相关文章 | 计量指标

粉煤灰/TiO2复合材料的制备及光催化性能研究 Preparation and photocatalytic properties of fly ash/TiO2 composite materials 王胜男 2026 (6):  747-755.  doi: 10.3969/j.issn.2097-2806.2026.06.006 摘要 ( 43 )   HTML ( 0 )   PDF(2030KB) ( 21 )   为了解决固体废弃物粉煤灰的资源化利用和有机染料的污染问题。以粉煤灰作为载体，市售TiO2 （P25）作为活性中心，通过机械混合法制备了粉煤灰负载TiO2 （FA/TiO2）复合材料，通过XRD、FT-IR、SEM、TEM、XPS和UV-vis DRS等手段对FA/TiO2复合材料的物相晶型、化学组成、微观形貌、元素组成和光谱响应进行了表征。以新品红（NF）染料作为目标污染物，评价了FA/TiO2复合材料的光催化活性和稳定性，研究了活性基团和降解机制，并提出了光催化机理。结果表明，TiO2 （P25）通过Si-O-Ti化学键牢固锚定在FA球状颗粒表面，提高了TiO2 （P25）颗粒间分散性，提高了紫外光响应能力，提升了光催化活性。在NF初始质量浓度为50 mg/L，FA/TiO2复合材料投加量为35 mg和初始pH为8.0条件下，FA/TiO2复合材料对NF降解率达到了97.97%，明显高于单一材料，循环使用5次后NF降解率仍达到了97.01%，表现出优异的光催化活性和稳定性。在超氧自由基（·O2-）和羟基自由基（·OH）等自由基作用下NF发生脱甲基化、羟基化和开环等反应被降解为小分子无机物。 To address the resource utilization of solid waste fly ash and the pollution of organic dyes, in this work, fly-ash-supported TiO2 （FA/TiO2） composites were prepared by mechanical mixing method using fly ash as carrier and commercially available TiO2 （P25） as active center. The crystal structure, chemical composition, microstructure, elemental composition and spectral response of FA/TiO2 composites were characterized by XRD, FT-IR, SEM, TEM, XPS and UV-vis DRS. The photocatalytic activity and stability of FA/TiO2 composites were evaluated by using new fuchsin （NF） dye as the target pollutant. The active species and degradation mechanism were studied, and the photocatalytic mechanism was proposed. The results showed that TiO2 （P25） was firmly anchored on the surface of spherical FA particles by Si-O-Ti chemical bond, which improved the dispersity of TiO2 （P25） particles, as well as the UV response ability and photocatalytic activity. When the initial mass concentration of NF was 50 mg/L, the dosage of FA/TiO2 composite was 35 mg and the initial pH was 8.0, the degradation percentage of NF by FA/TiO2 composite reached 97.97%, which was significantly higher than that by single material. After 5 cycles, the degradation percentage of NF still reached 97.01%, indicative of excellent photocatalytic activity and stability. In presence of free radicals such as superoxide radicals （·O2-） and hydroxyl radicals （·OH）, NF underwent demethylation, hydroxylation and ring opening reactions and was finally degraded into small inorganic molecules. 数据和表 | 参考文献 | 相关文章 | 计量指标

Through a comprehensive literature review, 23 major chemical components were identified. Using the SwissTargetPrediction and TCMSP databases, 443 potential targets were predicted, while 543 targets related to soothing, redness reduction, and acne elimination efficacies were screened from databases such as Genecards. A Venn diagram analysis reveals 109 overlapping targets. Based on these data, a compound-target network and a protein-protein interaction （PPI） network were constructed, followed by GO functional and KEGG pathway enrichment analyses. Network topology analysis identifies 16 core targets, which are primarily involved in biological processes such as the cellular response to lipopolysaccharide and the TNF signaling pathway. By correlating component concentrations with target activities, five active components with high abundance and significant modulation of core targets were selected as candidate quality control markers: oleuropein, hydroxytyrosol, luteolin-7-O-glucoside, apigenin-7-O-glucoside, and verbascoside. An HPLC method was subsequently developed and applied to analyze commercial cosmetics. The results show that these five components generally exhibit stable co-occurrence characteristics （either all detected or all undetected）, indicating their reliability as quality control markers for determining the presence of olive leaf extract in cosmetics. Based on these findings, this study proposes a classification and evaluation standard according to the addition level of olive leaf extract: standard addition products require the detection of all five components, while trace addition products use oleuropein as the single evaluation indicator. 数据和表 | 参考文献 | 相关文章 | 计量指标

The anti-inflammatory effect was evaluated by the nitric oxide （NO） inhibition assay, and the oil-control potential was assessed by quantifying the expression of genes related to sebum secretion, as well as intracellular lipids, and lipid droplets. Skin safety was evaluated through skin irritation tests. The results show that the Lignosus rhinocerus extract effectively scavenges DPPH free radicals, significantly reduces the production of glycation products, and promotes the expression of anti-aging-related genes （P<0.05）, demonstrating antioxidant, anti-glycation, and anti-wrinkle effects. Furthermore, the extract also promotes keratinocyte proliferation and increases hyaluronic acid synthase gene expression, indicating repair effects. Moreover, it significantly inhibits the production of nitric oxide induced by lipopolysaccharide （P<0.05）, showing anti-inflammatory effects. It significantly suppresses the expression of genes related to sebum secretion, and limits linoleic acid-induced sebum synthesis and lipid droplet formation （P<0.05）, indicating potential oil-control ability. The results of the human skin model irritation test further confirm the high skin safety of the extract. This study demonstrates that the Lignosus rhinocerus extract has anti-aging, repair, anti-inflammatory, and oil-control activities, combining efficacy with safety, which makes it a highly valuable candidate for cosmetic ingredient development. 数据和表 | 参考文献 | 相关文章 | 计量指标

However, its practical use in aqueous-based formulations is severely limited by its inherent volatility, water insolubility, and low bioavailability. To address these challenges, six surfactants commonly employed in cosmetic emulsions were selected to fabricate PEO-NEs. The anti-wrinkle efficacy of the resulting nanoemulsions was assessed through both biochemical assays-namely the scavenging of DPPH and ABTS free radicals, and the inhibition of elastase activity- and cell-based biological evaluations involving collagen secretion measurements in a human fibroblast model under UVA-induced stress. The findings reveal that employing PEG-40 hydrogenated castor oil as the surfactant enables the successful preparation of a uniformly dispersed, clear, and transparent PEO-NE with an average particle size of 22.5 nm. Biochemical analyses demonstrate that the nanoemulsion exhibits pronounced antioxidant activity, effectively scavenging both DPPH and ABTS free radicals. Specifically, a 4% （V/V） PEO-NE formulation achieves a DPPH scavenging rate of 93.68%, with a corresponding IC50 value of 1.29%. Meanwhile, a 1% （V/V） PEO-NE formulation achieves an ABTS scavenging rate of 84%, with a corresponding IC50 value of 0.31%. Furthermore, the nanoemulsion significantly inhibits elastase activity in vitro, indicating its potential to delay elastin degradation. Cell-based experiments confirmed that the PEO-NE markedly promotes collagen secretion in a UVA-damaged human fibroblast model.

衣康酸靶向修复受损发丝：基于巯基共价键合的力学增强机制 Targeted repair of damaged hair by itaconic acid: covalent thioether bonding mechanism for enhanced mechanical strength 黎曦, 吴雨闻, 成浩楠, 常晓维 2026 (6):  783-789.  doi: 10.3969/j.issn.2097-2806.2026.06.010 摘要 ( 78 )   HTML ( 4 )   PDF(3542KB) ( 30 )   该研究旨在解决化学处理导致的头发力学性能衰退问题。传统有机酸修复剂主要针对氢键等弱相互作用，对二硫键断裂引发的游离巯基修复效果有限。基于此，该文提出利用衣康酸（Itaconic acid）的α, β-不饱和羰基结构与游离巯基发生迈克尔加成反应，形成共价硫醚交联网络以增强头发机械性能。通过单根纤维拉伸测试（MTT690）、游离巯基定量（Ellman 法）及毛鳞片显微观察（HIROX），系统评估了衣康酸对还原损伤头发的修复机制。结果表明，衣康酸在质量分数 （w/%） 为2%，pH值为3.9时，修护效果最优，相较于受损头发的断裂载荷显著提升21%。重复三次衣康酸处理使受损发丝中游离巯基含量降低54.43%，证明其通过共价硫醚键与角蛋白交联。同时，多次衣康酸修护后，头发弹性梯度与断裂载荷分别显著提升16.67%和28.50%，远超琥珀酸（4.47%/13.85%）和柠檬酸（6.08%/15.85%），证明共价交联对提高力学性能起关键作用。此外，显微镜观察显示衣康酸有效修护受损毛鳞片的翘起与脱落，并保护毛鳞片减少疲劳循环损伤导致的横向断裂。这些发现揭示了衣康酸靶向修护受损发丝的作用机理，为开发高效头发修护产品提供了新策略。 This study aims to address the deterioration of mechanical properties in chemically treated hair. Conventional organic acid reparatives target weak molecular interactions （e.g., hydrogen bonds）, but exhibit limited efficacy in repairing free sulfhydryl groups generated by disulfide bond cleavage. Herein, we propose leveraging the α, β-unsaturated carbonyl structure of itaconic acid to initiate a Michael addition reaction with free sulfhydryl groups, thereby forming covalent thioether cross-linked networks to enhance the mechanical performance of hair. The reparative mechanism of itaconic acid on reductively damaged hair was systematically evaluated through single-fiber tensile testing （MTT690）, free sulfhydryl quantification （Ellman’s assay）, and cuticle microscopy （HIROX）. The results demonstrate that itaconic acid （w=2%, pH=3.9） maximally restores damaged hair integrity, significantly increasing the breaking load by 21% （P<0.05） compared to the damaged hair. Meanwhile, after multiple itaconic acid treatments, the elastic gradient and breaking load increase by 16.67% and 28.50%, respectively, compared with the damaged hair. These improvements surpass those achieved by succinic acid （4.47%/13.85%） and citric acid （6.08%/15.85%）, underscoring the critical role of covalent cross-linking. Microscopy further reveals that itaconic acid treatment effectively restores cuticle integrity by mitigating lifting and exfoliation, while protecting against transverse fractures induced by cyclic fatigue stress. Overall, these findings elucidate the targeted repair mechanism of itaconic acid on damaged hair, providing a novel strategy for developing high-performance hair reparatives. 数据和表 | 参考文献 | 相关文章 | 计量指标

羧甲基壳聚糖构效关系及化妆品应用研究进展 Research progress on the structure-activity relationships and cosmetic applications of carboxymethyl chitosan 曾玉梅, 伍飞飞, 方资元, 吴顺利, 朱美琴, 贾倩倩 2026 (6):  790-797.  doi: 10.3969/j.issn.2097-2806.2026.06.011 摘要 ( 79 )   HTML ( 0 )   PDF(1773KB) ( 28 )   随着消费者日益关注天然成分，甲壳素及壳聚糖衍生物等生物材料备受瞩目。羧甲基壳聚糖（CMCS）凭借其良好的生物相容性和优异的理化性能，成为极具潜力的化妆品原料。文章系统综述了CMCS的分子结构（取代位置、取代度、分子量、脱乙酰度）对其功能特性的影响，并重点梳理了近年来CMCS在化妆品中的多元化应用研究进展，包括其作为高效乳化稳定/增稠剂、强效保湿剂、抗氧化剂、抗菌剂，以及在活性成分缓释递送与防晒增效方面的作用。最后，探讨了CMCS应用于化妆品所面临的挑战并对其发展方向进行展望。 Carboxymethyl chitosan （CMCS）, a water-soluble derivative of chitosan, has garnered significant attention as a multifunctional biomaterial for cosmetic applications, driven by the growing consumer demand for natural and sustainable ingredients. Its performance is governed by structural parameters including substitution position, degree of substitution （DS）, molecular weight （Mw）, and degree of deacetylation （DD）. Research demonstrates the effectiveness of CMCS as an emulsifier and thickener, where its amphiphilic nature stabilizes emulsions and gels, potentially replacing traditional stabilizers like carbomer in oil-in-water systems. For moisturization, CMCS exhibits superior hygroscopicity and water retention compared to chitosan, with a performance rivaling that of hyaluronic acid. Studies confirm its antioxidant capacity through radical scavenging （against DPPH, superoxide, and hydroxyl radicals）, which is enhanced further by grafting natural antioxidants. CMCS shows significant antimicrobial activity against various pathogens, which is amplified when combined with metal oxide nanoparticles. As a delivery vehicle, it effectively encapsulates bioactive compounds like vitamin C and niacinamide for sustained release while enhancing skin permeability. In UV protection, CMCS-based high-molecular absorbers and nanocomposites substantially improve performance. Despite these advantages, critical challenges in cosmetic applications remain, such as performance inconsistencies due to uncontrolled synthesis conditions affecting structural parameters, the lack of standardized characterization in commercial products, and limited clinical validation with predominant reliance on in vitro data. Future development requires establishing quantitative structure-property relationships through precision synthesis, developing industry-wide characterization standards, generating robust human efficacy data, and advancing multifunctional CMCS composites. Addressing these gaps is crucial to unlocking the full potential of CMCS as a high-performance cosmetic ingredient. 数据和表 | 参考文献 | 相关文章 | 计量指标

An analytical system based on GC×GC technology was established, enabling efficient separation according to categories of alkenes-plus-alkanes, linear alkyl benzenes （LAB）, monocyclic aromatics, and bicyclic aromatics in HAB through a single injection. Simultaneously, qualitative identification and quantitative analysis of each component were achieved. The results showed that the hydrocarbon fractions of HAB primarily consisted of alkenes-plus-alkanes, LAB, monocyclic aromatics, and bicyclic aromatics. Using the established method, the content of each category, i.e., alkenes-plus-alkanes, LAB, monocyclic aromatics and bicyclic aromatics, was determined for three HAB samples （designated as HAB-1, HAB-2, and HAB-3）. Based on chromatographic peak area: LAB exhibited the highest mass fractions in three samples （94.05% in HAB-1, 84.59% in HAB-2, and 66.43% in HAB-3）. Based on carbon number distribution: The peaks of HAB-1 mainly distributed in the range of C17-C28; the peaks of HAB-2 mainly distributed in the range of C19-C33; the peaks of HAB-3 mainly distributed in the range of C27-C50. Compared with traditional one-dimensional gas chromatography （GC）, GC×GC demonstrated significant technical advantages and broad application prospects in separating complicated mixtures due to its enhanced peak capacity and superior resolution. This method could provide technical support for in-depth understanding of hydrocarbon composition in HAB. 数据和表 | 参考文献 | 相关文章 | 计量指标
