表面活性剂淋洗修复土壤中重金属污染研究进展

Research Progress of Surfactant Washing for Remediation of Heavy Metal Pollution in Soil

随着工业的不断发展,土壤重金属污染问题日益严峻,寻找到一种高效处理重金属污染土壤的方法刻不容缓。土壤淋洗是土壤修复的一种重要方法,其中表面活性剂作为一种相对环保的处理剂被广泛地应用在土壤淋洗之中。文章概括了土壤重金属的修复方法与表面活性剂的种类,阐述了表面活性剂淋洗土壤的机理,总结了不同类型表面活性剂淋洗土壤重金属的应用,最后对表面活性剂淋洗土壤中重金属的应用前景与发展趋势进行了展望。

With the development of industry,soil contamination with heavy metals is building up.It is urgent to find a method for treating soil contamination with heavy metals efficiently.Soil washing is an important method for soil remediation.As a relatively environmental protection agent,surfactant is widely used in soil washing.This paper generalized the methods of soil heavy metals,remediation and the types of surfactants,expounded the mechanisms of washing soil by surfactants,summarized the application of different surfactants in washing heavy metals from soil.Finally,the application prospects and development trends of surfactant washing heavy metals from soil were prospected.
