摘要/Abstract

摘要：

煤矿液压支架乳液在使用的过程汇入矿井水中，大幅度增加了处理难度。粉末活性炭（AC）具有比表面积大、吸附能力强等优点，可以应用于含乳液矿井水的处理中，但存在吸附后固液分离难以及AC再生回用难的问题。基于此，本研究以AC、FeCl₃·6H₂O、FeCl₂·4H₂O为原料，通过化学共沉淀法制备了活性炭负载Fe₃O₄复合材料（AC@Fe₃O₄），并应用于液压乳液废水的吸附处理。结果表明，磁性活性炭对乳液的吸附在90 min时达到吸附平衡，当乳液的初始体积分数为0.5%，温度为25 ℃，振荡速度为200 r/min时，对乳液的吸附量为1.07 mL/g。吸附动力学研究表明，磁性活性炭对乳液的吸附更符合伪二级动力学模型，表明其对乳液的吸附主要是化学吸附，Langmuir等温线模型对磁性活性炭吸附乳液的拟合度较高，通过拟合计算得到的理论饱和吸附量为1.51 mL/g，而实验中优化吸附量也达到1.07 mL/g。吸附平衡后分离出的AC@Fe₃O₄在甲醇中乳液的脱附率可以达到90%以上，吸附剂可以重复利用，经过5次循环仍能保持良好的吸脱附性能，并且在外加磁力的作用下可实现液固分离，回收利用简单方便。

Abstract:

The treatment of mine water has become increasingly difficult due to the afflux of hydraulic support emulsion. With the advantages of large specific surface area and adsorption capacity, powdered activated carbon （AC） has been widely used in water treatment. However, for ordinary AC, there are difficulties in separation and recycling after adsorption of organic pollutants. Herein, activated carbon supported Fe₃O₄ （AC@Fe₃O₄） was prepared with chemical coprecipitation by using AC, FeCl₃·6H₂O and FeCl₂·4H₂O as raw materials, and the product was used to adsorb the hydraulic support emulsion from water. The results showed that the adsorption equilibrium could be reached at 90 min. At the volume fraction of emulsion of 0.5%, temperature of 25 ℃ and oscillation rate of 200 r/min, the adsorption capacity was 1.07 mL/g. The study of adsorption kinetics showed that the adsorption of emulsion at AC@Fe₃O₄ was more consistent with pseudo-second-order model, indicating that the adsorption of emulsion on magnetic activated carbon was mainly chemical adsorption. The Langmuir isotherm model had a high fitting degree for the adsorption of emulsion on magnetic activated carbon, in which the theoretical saturated adsorption capacity calculated by fitting was 1.51 mL/g. In the experiment, the optimized adsorption capacity could reach 1.07 mL/g. After adsorption, external magnetic force was used to realize complete liquid-solid separation. In methanol, more than 90% emulsion could be desorbed from the AC@Fe₃O₄ after adsorption. After 5 cycles, the AC@Fe₃O₄ still maintained excellent performance of adsorption and desorption. This work could provide a novel strategy for efficient recycling and reutilization of activated carbon in treatment of the waste water containing emulsion.
