摘　　要：本文综述了国内近十年关于粘土矿物和蛭石表面性质及表面改性的资料,分析了粘土矿物和蛭石表面改性的原理、方法和影响因素,研究了烷基季铵盐阳离子在粘土矿物和蛭石层间的排布模式,总结了有机粘土和有机蛭石吸附有机物的吸附理论和机理,为有机粘土和有机蛭石在废水处理和聚合物填充增强改性中的应用提供理论依据。This paper has reviewed the data on the researches of the surface properties and their modification of clay minerals and vermiculite in last 10 years, analyzed the principles, methods and influential factors of the surface property modification of clay minerals and vermiculite, studied the layout models of the cations of alkyl quaternary ammonium salts in the interlayer of clay minerals and vermiculite, summarized the theories and mechanism of organic adsorption by clay and vermiculite, and provided theoretical evidence for treating the polluted water and strengthening and modifying polymers by using and infilling organic clay and vermiculite respectively.
