表面活性剂用于石油污染土壤修复的研究进展

Research progress of surfactant for remediation of petroleum contaminated soil

本文综述了近年来以表面活性剂为增强剂进行污染土壤/场地修复的研究进展。表面活性剂可以增强土壤对污染物的解吸,并通过提高污染物的生物有效性促进有机物的生物修复。生物表面活性剂由于其较低的临界胶束浓度(CMC)值和较好的生物相容性等良性特性也被用于土壤修复。为了提高土壤洗液的整体去污性能,通常采用混合表面活性剂体系以及表面活性剂与其他添加剂的联合使用,表面活性剂技术在土壤修复中的应用前景广阔。

This paper reviews the research progress of remediation of contaminated soil/site using surfactants as enhancers in recent years.Surfactants can enhance soil desorption of contaminants and promote bioremediation of organic matter by increasing bioavailability of contaminants.Biosurfactants are also used in soil remediation due to their benign properties such as lower critical micelle concentration(CMC)values and better biocompatibility.In order to improve the overall decontamination performance of soil lotion,the mixed surfactant system and the combination of surfactants and other additives are usually used,the application of surfactant technology in soil remediation has broad prospects.
