污染土壤中重金属的化学提取技术及其实际应用综述

Chemical extraction method in remediation of heavy metals contaminated soil and the practical application

化学提取法是重金属污染土壤的主要修复方法之一,本文重点综述了几类常用的化学提取剂,介绍它们在实验室的研究以及实际的工业应用。可提取态重金属对化学提取的效率有着重要影响,修复后的土壤也需要进行合理的评价,因此本文对可提取态重金属的研究以及修复效果评价的方法也进行了综述。

Chemical extraction is a significant and effective method for the remediation of heavy metal contaminated soils. This review summarized the laboratory studies and practical industry applications of the eluent. The extractable metals can influence the extraction process as well as the remediation effect,soil contaminated with heavy metals after remediation also needs a reasonable evaluation. This paper also reviewed the research on extractable heavy metals and evaluation method.
