腐植酸在重金属污染土壤修复中的研究进展

The Research Progress of Humic Acid in the Remediation of Heavy Metal Contaminated Soil

随着中国工业化和城市化进程的加快,不可避免的土壤重金属污染给生态系统带来极大的危害。腐植酸因其独特的结构和性质,在土壤重金属污染修复中具有非常重要的作用。本文结合国内相关研究进展,分别从土壤重金属污染、腐植酸修复土壤重金属的作用机理及其应用效果3方面进行总结分析,提出腐植酸修复重金属污染土壤的前景展望。

With the acceleration of industrialization and urbanization in China,the heavy metal pollution in soil is bringing great harm to the ecosystem inevitable.Humic acid plays a very important role in the remediation of heavy metal contaminated soil for its unique structure and properties.In this paper,based on the research progress in China,the heavy metal pollution in soil,the mechanism of humic acid remediation of heavy metals in soil and the application effect of humic acid remediation of heavy metals in soil were analyzed and summarised.Furthermore,the prospect of humic acid remediation of heavy metal contaminated soil was suggested.
