摘　　要：在相同的光亮镀镍液中分别加入浓度依次递增的铜、锌、铁、铬、铜的标准溶液。用原子吸收光谱法连续测定镀液中铜、锌、铁、铬、铅杂质的含量 ,优选出最佳的仪器工作条件 ,讨论了共存元素的干扰及消除。该方法简单 ,准确度和精密度高 。Increasing amount of copper, zinc, iron, chromium and lead standard solutions were separately added in the same nickel plating baths, subsequently, copper, zinc, iron, chromium and lead impurities were continuously determined by atomic absorption spectrometry. Operating parameters of the analytical apparatus were optimized. Interference of coexisting elements was discussed. This method is simple, accurate, and has good application value.
