环糊精在污染土壤修复中的研究进展

The Application of Cyclodextrin and Its Derivatives in Remediation of Contaminated Soils

环糊精由于其具有特殊的分子空腔结构,可以增容及解吸吸附在土壤中的有机污染物,并对土壤表层的有机污染物具有一定的光解促进作用,通过对环糊精改性还能达到同时去除土壤中有机物和重金属污染物的效果。目前环糊精作为环境友好型材料已经广泛的应用于环境治理中,文章介绍了环糊精及其衍生物在污染土壤修复方面的应用。

Cyclodextrin have special molecular cavity structure, made it Can enhance the dissolution and desorption of organic pollutants in soil, it also has a certain photolysis of promotion to the organic pollutants of soil surface. The cyclodextrin modified can achieve simultaneous removal of organic matter and heavy metal pollutants in soil effect. At present, cyclodextrin Has been widely used in environmental governance as an environmental friendly materials, this paper introduces the application of cyctodextrin and its derivatives in remediation of contaminated soils.
