摘要：
On the basis of the HSAB principle, a method for extraction of metal ions with diethyldithiocarbamic acid (DDTC) consisting of the preconcentration and separation of trace metal ions was developed. Metal ions extracted into CCl4 were back-extracted into Cu-EDTA solution which was applied to isotachophoretic analysis. This method made possible the separation of Cd-II, Fe-II, Pb-II and Zn-II at 10(-6) mol dm(-3) level.
