摘要
近年来,土壤重金属污染因其对人类健康产生为害受到了更多的关注。腐殖质因其含有多种官能团,对金属离子具有螯合与络合特性,常作为一种环境友好型修复剂受到广泛关注。本文概述了近20年国内外关于腐殖质和改性腐殖质在土壤重金属污染修复的研究进展,总结了提高腐殖质的活性、稳定性及迁移性等的改性技术,并对影响反应效率的因素做了简要的探讨,对腐殖质未来的研究方向进行了展望,以期为今后的研究作为参考。
Heavy metal contamination in soil has attracted much attentions around the world due to its serious threat to human health in recent years.Being used as the eco-friendly remediator,humic substances have received widespread attention because of its functional groups which could complex with metal irons.This article reviews the research advances in the repairing effects of humus and modified humus on heavy metal contaminated soil at home and abroad in the past 20 years,summarizes the modification technology in improving the activity,stability and mobility of humic substances,briefly discusses the factors affecting the reaction efficiency,and prospects the direction for the future research of humus,so as to provide a reference for the future research.
