摘要
综述了土壤重金属的来源、危害以及纤维素、活性炭、黏土类矿物重金属钝化材料的研究进展。探讨了不同改性方法对土壤修复剂的重金属钝化性能的影响,并阐述了土壤重金属的相关修复机理。最后对绿色土壤重金属修复剂目前所面临的问题和未来研究方向进行了展望。
Abstract
The sources and hazards of heavy metals in soil are described,and the research progress of cellulose,activated carbon,and clay minerals in the passivation of heavy metals are reviewed.The effects of different modification methods on the passivation performance of soil remediation agents to heavy metals are discussed,and the related remediation mechanisms are also expounded.Finally,the existing problems and future research directions of green repairing agents for remediation of heavy metals in soil are prospected.
