摘要:
对铅锌矿区周边土壤中Pb、Cd、As等重金属分别进行了总量及其形态研究.重点考察重金属固化剂六硫代胍基甲酸(SGA)和二甲基二硫代氨基甲酸盐(SDD)对不同形态重金属的稳定化性能.研究结果表明,采集的土壤样品受Pb、Cd、As等重金属污染较为严重,样品S1中As、Pb含量分别超过土壤环境质量三级标准10.17倍、3.29倍,Cd超过土壤环境质量二级标准28.7倍.SGA对弱酸态As、Cd和Pb的综合稳定化性能优良,对3种重金属的稳定化率最高达到92.73%、82.35%和81.48%; SDD对可氧化态Cd稳定化性能优于SGA,最高稳定化率为88.89%.SGA作为一种新型重金属螯合捕集剂,可以应用于重污染土壤中重金属的污染控制和修复.
Abstract:
The characteristics and distribution of different forms of heavy metals in soils contaminated from mined area were investigated,and were evaluated according to the BCR sequential extraction protocol. Stabilization performance of sixthio guanidine acid(SGA)and sodium dimethyl dithio darbamate(SDD)were compared.The results indicated that the soils were contaminated seriously by lead,cadmium and arsenium,the contents of As and Pb exceeded 10.17 times and 3.29 times than that of Environmental Quality Standard for Soils(GB 15618-1995)with the Grade Ⅲ standard respectively,and the content of Cd exceeded 28.7 times.SGA had an excellent comprehensive property in stabilization of the heavy metals of acid soluble in soils,the stabilization ratios for As,Pb and Cd were 92.73%,82.35% and 81.48% respectively,while SDD had a better property in immobilization of the heavy metals of oxidizable compared with SGA.As a novel heavy metal chelating agent,SGA can be used in remediation of soils contaminated by heavy metals.
