摘　　要：简述了膨润土的结构和基本性质,介绍了几种膨润土的改性方法,总结了天然膨润土和几种改性膨润土对水中有机物的吸附效果,探讨了pH、初始浓度及吸附剂用量等对膨润土吸附有机物效果的影响,论述了膨润土的吸附机理和规律,并展望了其应用前景。The structure and property of bentonite were showed. Several modifying methods of bentonite were mtroduced. The adsorption effects of organic pollutants from wastewater by natural bentonite and several kinds of modified bentonite were summarized. The influences of pH, initial concentrations and adsorbent amounts etc. on the adsorption of bentonite were discussed. Moreover, the adsorption mechanisms and rules were dissertated, and applying prospect of bentonite in wastewater treatment were also presented.
