为了探明 HEDP（羟基乙叉二膦酸）淋洗修复镉污染土壤的可行性，采用振荡提取和柱实验的方法，研究了 HEDP 不同浓度、土液比、淋洗时间和淋洗次数对土壤镉去除率的影响。结果表明：HEDP 浓度为3％、土液比为1∶3、淋洗时间为180 min、1次淋洗为镉污染土壤修复的最佳条件。可利用 HEDP 作为淋洗剂修复镉污染土壤。

In order to explore the washing feasibility of HEDP on remediation of Cd contaminated soil, batch and column experiments were conducted to investigate the removal rate of Cd in soil under various operating conditions,including HEDP concentration,ratio of soil to solution,leaching time and times. The results showed that the optimum conditions were as follows:HEDP concentration was 3%,the ratio of soil to solution was 1:3,leaching time was 180 min and leaching once can achieve the best removal rate of Cd,HEDP could be used in washing remediation of Cd contaminated soil.
