摘　　要：试样用王水溶解,在氨性溶液中实现铜铬的分离。实验表明,加氨水可以消除铬的干扰,从而确定了碘量法快速测定铜铬混合粉中铜的分析方法。The test sample was decomposed by aqua regia,the Copper and chromium were separated in ammonia solution.The results show that the disturbance of chromium can be eliminated by adding ammonia,so the copper content of the copper-chromium mixed powder can be determined by iodimetry rapidly.
