摘要
报道用微分电位溶出分析法测定配合物在玻炭电极上氧化溶出电位与配位体浓度之间的关系，研究配合物的逐级稳定常数和参与形成配合物的配位体数目。研究了Ｃｕ（Ｈ２Ｓａｌ）２＋２和Ｃｄ（ＳＣＮ）２－４配合物体系，测定结果与文献［３。
A new method for determination of stability constants of complex by differential potentiometric stripping analysis was described. According to the relationship between the oxidative stripping potential of the metal ion and the concentration of the ligands, the stability constants and the coordination numbers of Cu(H 2Sal) 2+ 2 and Cd(SCN) 2- 4 complexes were successfully determined. The experimental data were almost concordant with the data of other independent methods in literatures.
