| 摘 要： | 化学钝化修复是一种基于向污染土壤中添加稳定化剂,通过吸附、沉淀、络合、离子交换等一系列反应,使污染物向稳定化形态转化,以降低污染物的可迁移性和生物可利用性,从而达到污染土壤修复目的的方法.磷酸盐、碳酸盐和硅酸盐材料是目前常用的重金属化学稳定化剂.本文概述了国内外关于该3类材料修复重金属污染土壤的作用效果、分子机理、应用实例、影响因素及其对土壤性质影响等方面的研究进展,并讨论了该3类材料原位修复土壤重金属的长期稳定性及二次污染问题. |

| Abstract: | Amendment-induced immobilization of heavy metals has been considered as a cost-effective method for remediation of contaminated soil.Phosphate-,carbonate-,and silicate-based amendments are commonly used materials for the heavy metal immobilization in order to reduce metal mobility and bioavailability.In this paper,a review was presented on the amendment types,treatment effectiveness,molecular mechanism,impact factors,field demonstration,and effects on the soil properties.The long term stability and secondary pollution problems of in situ immobilization with phosphate-,carbonate-,and silicate-based materials were also discussed. |
| Keywords: | heavy metals contaminated soil immobilization phosphate-based amendment carbonate-based amendment silicate-based amendment |
