摘要:

为了解洗发水中元素含量状况,建立了电感耦合等离子体质谱法同时测定洗发水中52种元素的分析方法。通过优化微波消解及ICP-MS条件,选用6 mL HNO3和2 mL H2O2消解样品,Ge和Re作为内标定量分析了57批次市售洗发水中Li、Be、B、Al、Sc、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、Ga、As、Se、Rb、Sr、Y、Ru、Pd、Ag、Cd、In、Sn、Sb、Te、Cs、Ba、La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu、Hf、Ir、Pt、Au、Hg、Tl、Pb、Bi、U 52种元素含量。结果表明,该方法在1~100 μg/L (Se、Zn、Fe、Al:1~1 000 μg/L;Hg:0.1~4 μg/L)范围内线性关系良好,相关系数均>0.999 0,方法检出限不高于75 μg/kg。低、中、高浓度加标回收率范围为81.3%~114.1%,RSD<6% (n=6)。该方法简单、准确、灵敏度高、重复性好,适用于洗发水中52种元素的快速批量测定。洗发水样品中Pb、Cd、Hg、As检测结果均符合规定,化妆品禁用组分Ni、Cr、Sb、Te、Be、Tl和16种稀土元素含量低,某些类型或品牌洗发水中Se、Zn、Fe、Al含量较其他样品高。

Abstract:

To investigate the elemental contents in shampoo, an analytical method for the simultaneous determination of 52 elements in shampoo was established using inductively coupled plasma mass spectrometry (ICP-MS). Through the optimization of microwave digestion and ICP-MS operational parameters, 6 mL of nitric acid and 2 mL of hydrogen peroxide were adopted to digest the samples; the No gas analysis mode and He mode were selected as instrumental analysis modes; and Ge and Re were used as online internal standards. The concentrations of 52 elements (namely Li, Be, B, Al, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Y, Ru, Pd, Ag, Cd, In, Sn, Sb, Te, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ir, Pt, Au, Hg, Tl, Pb, Bi, and U) in 57 shampoo samples were determined and quantified by ICP-MS under the opimal experimental conditions. The results indicate that under the optimized conditions, the linearity of all 52 elements is good in the range of 1-100 μg/L (1~1 000 μg/L for Se, Zn, Fe, and Al; 0.1~4 μg/L for Hg), with the correlation coefficients exceeding 0.999 0. The limits of detection of the method are no higher than 75 μg/kg. The spiked recoveries at low, medium and high concentrations (n=6) range from 81.3% to 114.1%, with relative standard deviations of no more than 6%. This method is simple, accurate, sensitive and reproducible, making it suitable for the rapid, high-throughput determination of 52 elements in shampoo. The determination results show that the concentrations of Pb, Cd, Hg, and As in all samples conform to the standard. The contents of prohibited cosmetic ingredients, including Ni, Cr, Sb, Te, Be, Tl and 16 rare earth elements, are low. In contrast, the concentrations of Se, Zn, Fe, and Al are higher in certain types or brands of shampoo samples than in others.
