摘要
对土壤中铅镉的形态和有效态的提取与分离进行了研究。比较了不同提取剂的提取能力，选择了铅、镉的最佳形态和有效态提取剂，建立了土壤中铅、镉的形态连续提取方法。并对提取剂的提取机理进行了初步探讨。
The extraction and seperation of form and available state of Pb,Cd in soil are studiedin this paper. The extracting ability of different extractants is compared. The optimum extrac-tants of form and available state of Pb, Cd are selected. The continuous extracting methods ofthe form of Pb,Cd in soil are established. The extracting mechanism of the extractants is stud-ied tentatively.
