| Abstract: | In potassium thiocyanate media, the polarographic waves of the mixtures of cadmium and nickel were measured by linear sweep polarography at a dropping mercury electrode.Excel programming was then applied to the resolution of the overlapping polarographic waves of metal mixtures.The mixture samples with different concentration ratio were analyzed by the proposed method and satisfactory results were obtained. |
