| Abstract: | 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. |
