有机黏土矿物修复有机污染研究进展

Advancement in the Study on Organoclay Minerals in Remediation of Organic Contaminated Soils

本文综述了有机黏土矿物对环境中有机污染物吸附的研究进展。具体介绍了黏土类型,改性剂种类,改性条件以及有机污染物性质对吸附性能的影响,有机黏土矿物对有机污染物的吸附机理,并就溶液pH和温度的影响机制进行了分析。文章最后对有机黏土在环境污染治理方面的作用研究作了展望。

A review is presented here of advancement in using organoclay minerals to absorb organic pollutant in the environment. Several factors that may influence adsorption capacity of organoclay minerals are introduced, including type of the clay minerals, kind of the modifiers, conditions of modification and characteristics of organic pollutants. In addition, mechanisms of organoclays adsorbing organic pollutants and mechanisms of pH and temperature of the solution affecting the formers are discussed. Finally, a brief introduction is given to potential prospects of the use of organoclay minerals to remove environmental pollutants.
