摘要：

通过室内模拟实验，比较研究EDTA、酒石酸和EDTA与酒石酸的联合作用对污染土壤中的重金属Cu、Pb的释放影响。结果表明，随着EDTA和酒石酸浓度的提高，都促进了土壤中Cu和Pb的释放，EDTA对Pb的释放效果要好于Cu，酒石酸对Cu的释放效果好于Pb。EDTA与酒石酸的联合作用能显著提高土壤中Cu的释放，最大释放率为48%，对Pb的释放率与EDTA单独作用时相差不大。

Abstract:

According to study the effect of EDTA, tartaric acid and the associative action of EDTA and tartaric acid on Cu and Pb releasing from soil through batch experiments. The results showed that the releasing amount of Cu and Pb increased with the increase of EDTA or tartaric acid concentration. EDTA promoted more Pb than Cu releasing from soil, while tartaric acid did the reverse. The associative action of EDTA and tartaric acid can notably increase the releasing amount of Cu from soil, the biggest releasing rate was 48%, and it almost released the same amount of Pb with EDTA in soil alone.
