摘要
对国内外在冻融作用对重金属的影响方面的研究成果进行了系统评述。通过介绍了冻融作用的基本概念,梳理了由冻融作用引起的土壤理化性质的变化从而导致重金属在土壤中吸附、解吸、赋存等方面的迁移转化机制,分析了冻融作用条件下不同土壤重金属修复技术的应用效果,并指出了当前研究存在的主要问题和研究空白。最后结合当前情况,展望了未来相关研究领域的主要内容和重点发展方向。
This paper systematically reviewed the domestic and foreign researches related to the effects of freezing and thawing on heavy metals,and further introduced the basic concepts of freezing and thawing,and analyzed the changes in soil physical and chemical properties caused by freezing and thawing,which leads to the migration and transformation of heavy metals in the soil,such as adsorption,desorption,occurrence.Moreover,this paper analyzed the current application of remedy technology on heavy metal under freezing and thawing conditions,and pointed out the main problems and research gaps in current research.Finally,combined with the current situation,the main content and key development directions of related research fields in the future were prospected.
