摘　　要：探讨采用Excel规划求解法对镉、镍2组分混合物溶液的线性扫描极谱数据进行定量解析.实验以硫氰酸钾为底液,滴汞电极为工作电极,以1V/s的速度由-300mV向-900mV进行线性极谱扫描并采集电流数据.测定了多种不同浓度比例的镉、镍混合溶液,均获得较好的结果.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.
