摘　　要：基于改性用表面活性剂的种类不同,介绍了改性粘土在芳香族化合物吸附去除中的应用,探讨了改性提高吸附性能的作用机理,讨论了pH、温度、离子强度等水化环境对去除效果的影响。认为加强表面活性剂改性粘土的稳定性,是急需解决的问题之一;表面活性剂改性粘土在污染水体处理中的应用前景非常广阔。According to the different types of surfactants used in clay-modification, the application of modified clay in aromatic compounds removal by sorption was introduced, the modification mechanism in improving the adsorption properties and the influence ofpH, temperature, ionic strength on aromatic compounds＇ removal efficiency were discussed. Enhance the stability of the surfactant modified clay was one of the urgent problems; surfactant modified clay bad very broad prospects of application in the treatment of polluted water bodies.
