摘　　要：综述了环糊精及其衍生物在土壤弱极性有机物治理中的应用和原理。环糊精可与土壤中弱极性有机污染物形成主客包合物,从而增加其水溶性促进其从土壤中解吸去除;能够同时去除金属离子;能够改变有机污染物理化性质促进其光解;可降低有机污染物毒性促进其微生物降解。Application and principles of cyclodextrins in remediation of low polar organic pollutants contaminated soil was reviewed. The organic pollutants could form inclusion complex with cyclodextrin, which increased the solubility and enhanced the remove of pollutants adsorbed in soil. The cyclodextrin formed coordination compounds with inorganic pollutants （heavy metals）, which were removed with the organic pollutants simultaneously. And the formation of inclusion complexes also increased the photo- degradation, reduced the toxicity and increased the biodegradability of the low - polar organic pollutants.
