摘　　要：通过向土壤中施加螯合剂促进植物对重金属的吸收是目前一项比较有发展前景的土壤修复技术。本文综合介绍了近年来EDTA等多种螯合剂在植物修复重金属污染土壤中的应用,同时介绍了一种新型易降解的螯合剂EDDS的研究进展,最后对存在的问题进行了讨论,并对未来的研究重点进行了展望。Applying chelating agents into the soil to promote plant absorption of heavy metals is currently a very promising technology of soil remediation. A review was presented of application of various chelating agents, such as EDTA, EDDS, to heavy-metal contaminated soils to stimulate phytoremediation of the soil in recent years. In addition, an introduction was made to the development of a new decomposable chelating agent, EDDS, and in the last part some existing problems were discussed and foci of the future study were prospected.
