综述了国内外有关膨润土在环境污染治理方面的研究进展。膨润土及其改性产物 (活化膨润土、有机膨润土、交联膨润土、有机交联膨润土 )由于具有良好的吸附性能,在环境污染治理方面得到了越来越广泛的应用。在对含有机污染物、重金属的废水处理中,膨润土是一种高效吸附剂。欧美国家在土壤和地下水污染的防止和修复方面取得了较大的进展。近年来,有关膨润土用于放射性废物处置的理论研究活跃。

A study on the remediation of contaminated environment by using bentonite both at home and abroad is reviewed. Having excellent adsorptive properties, natural bentonite and modified bentonite (such as act ivated bentonite, organobentonite, cross-linked bentonite and organic cross- linked bentonite) have been widely used in environmental control . Bentonite is an effective adsorbent for the removal of organic contaminates and heavy metals from wastewater. Researches have been conducted on the remediation of polluted soils and underground water. Besides, theoretical studies of bentonite used for radioactive waste treatment have been an active subject in recent years.
