摘要
重金属镉原位钝化修复是指向土壤中施加一些活性钝化修复材料,通过改变镉在土壤中的赋存状态,降低土壤中镉的生物有效性。该文对重金属镉污染土壤原位钝化修复中不同来源的钝化剂进行了分类,概述了它们各自对重金属镉污染土壤的作用机理及其钝化修复效果。全面分析了目前该领域存在的主要问题,并对其发展前景进行了展望。
In situ immobilization of heavy metal cadmium in contaminated soils with active amendments could decrease the bioavailability of cadmium by changing occurrence state of heavy metals in soils. In this paper, the different sources of heavy metals are classified by in situ immobilization remediation of cadmium in contaminated soils. The remediation mechanism and the effect were summarized on heavy metal contaminated soil. Moreover, the main problems and development prospect were comprehensively analyzed in this area.
