摘要/Abstract

摘要： 采用土柱淋洗的方法,研究有机膦酸PAPEMP淋洗去除重金属镉的适宜条件,分别研究了PAPEMP不同土液比、淋洗时间和淋洗次数对土壤中重金属镉的去除效果。结果表明,以质量分数为7%PAPEMP溶液为淋洗剂,土液比为1∶4,淋洗时间为240min的条件下,1次淋洗时土壤中镉的去除率最高。PAPEMP可以应用于淋洗修复镉污染土壤。

Abstract: Using soil column leaching method, the best leaching conditions have been studied with the organic phosphonic acid PAPEMP, including different ratio of soil to solution, leaching time and leaching frequency on the Cd removal rate, respectively. The research results showedwhen the quality percentage of PAPEMP was 7%, the ratio of soil to solution of 1∶4, the leaching time of 240 min and leaching once, the removal rate of Cd was the highest. PAPEMP can be used in leaching remediation of Cd contaminated soils.

Key words: PAPEMP, Soil column leaching, Cd-contaminated soil
