摘　　要：本方法采用硝酸—硫酸混合酸溶解试样 ,以酒石酸钾钠络合主体钼 ,用电解法和丁二酮肟重量法分别测定铜和镍的含量。用电解铜后的溶液继续分析镍的含量 ,既简化了分析程序 ,又排除了钼和铜对镍的干扰 ,实现了对钼铜合金中铜和镍的联合测定。本方法分析钼铜合金试验原理可靠 ,操作简便 ,精密度好 ,准确度高。A method for analyzing Mo-Cu alloy is proposed in this paper. The sample is dissolved in mixed acids, Using sodium potassium tartrate to hide the matrix of Molybdenum, Copper and Nickel's content can be determined by electroanalysis and weight methods. It proves to simplify the analysis, avoid interference among the elements of Mo, Cu and Ni, and fulfill the united determination of Cu and Ni in Mo-Cu alloy. The method is reliable, simple and accurate.
