摘　　要：环境中有机污染物、阴离子污染物以及重金属污染物的存在会对人类生命安全造成损害,因此受到研究者的重视。近年来,国内外研究人员使用不同材料对这些污染物进行吸附,其中有机黏土矿物因具有成本低、粒径小、比表面积大、阳离子交换容量高等优势备受瞩目。相比于未改性的黏土矿物,有机黏土矿物对有机污染物、阴离子污染物以及重金属污染物具有更高的吸附效率。文章主要综述了阳离子表面活性剂、阴离子表面活性剂、阳、阴离子表面活性剂、双子表面活性剂、非离子表面活性剂以及聚合物和硅烷偶联剂对黏土矿物的改性方法及改性机理,重点概述了有机黏土矿物在污水治理方面的应用,最后基于实际应用现状,对有机黏土矿物的发展与挑战进行了展望。The existence of organic pollutants and anion pollutants in the environment will cause damage to human life safety,so it is valued by researchers.In recent years,researchers at home and abroad have used different materials to adsorb these pollutants.Among them,organic clay minerals have attracted much attention due to the advantages of low cost,small particle size,larger surface area,and high cationic exchange capacity.Compared with unavailable clay minerals,organic clay minerals have higher adsorption efficiency for organic pollutants and anion pollutants.The article mainly summarizes the cationic surfactant,anion surfactant,yang,anion surfactant,twin surfactants,non-ion surfactants,and polymers’modification methods and modification mechanisms for clay minerals.The application of clay minerals in sewage management is mainly summarized.finally based on the current status of the actual application,to look forward to the development and challenges of organic clay minerals.
