有机粘土矿物对污染环境修复的研究进展

CONTAMINATED ENVIRONMENT REMEDIATION WITH ORGANOCLAY MINERALS

本文综述了国外在有机粘土矿物对污染环境修复研究方面的最新进展.具体介绍了利用表面活性剂制备有机粘土矿物的方法,不同类型有机粘土矿物的特征,有机粘土矿物对各种有机污染物的吸附行为及机理,在地下水污染的现场修复、土地填埋防渗添加材料和去除工业废水有机污染物等方面的应用.

Study on remediation of contaminated environments using organoclay minerals was reviewed. We introduced the methods for preparing organoclays using surfactants, the physicochemical properties of different organoclays, the sorptive behaviors and mechanisms of organoclays for organic contaminants, and the application to in-situ groundwa-ter remediation, as clay liner additives in landfill and to removal of organic contaminants from industrial wastewaters.
