摘　　要：针对传统铜离子含量测定方法在氨式碳酸铜溶液中铜离子含量测定过程中所存在的问题,考察影响氨式碳酸铜溶液中铜离子含量测量结果的测定条件,明确其影响机理,对传统测定方法进行改进,并用质量法对该方法的准确性进行验证.结果表明:改进的测定方法与传统方法相比具有准确性高、简便、快速等优点.The defects in the traditional analysis method for the content of copper ions in ammonia copper carbonate solu-tion were reviewed. The conditions which affect the accuracy of the copper ions analysis of ammonia type copper carbonate solution were investigated,and the mechanism was discussed. A new method was proposed and the accuracy of the proposed method was verified with the gravimetric method. Results showed that the accuracy of the analysis was improved with the improved method compared with the traditional method.
