摘要
土壤重金属活化移除技术作为一种快速有效的污染土壤治理技术,越来越受到重视。综述了近年来螯合剂、低分子有机酸、表面活性剂等不同活化剂对重金属的活化移除效果,包括活化剂对部分重金属形态变化的影响以及与植物联合修复的效果,并综合考虑其本身的生物降解性和生态毒性等优缺点,以期为研究重金属污染土壤修复技术提供参考。
As a potential cleanup technology for the removal of heavy metals from contaminated soils,the activating agents was paid more and more attention to. This paper reviewed the most relevant studies towards the use of activating agents application for remediation of soils,including the influence on the shape variation of occurrence of heavy metals in the soils and the removal efficiency when used in combination with phytoremediation. At the same time,the advantages or disadvantages of each compound for the most important applications were discussed to provide references for study on heavy metal contaminated soil remediation technologies.
