【Abstract】 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.更多还原
