ICP-AES测定铜-锌合金中锌及杂质元素砷、铅、锑和铋

Determination of Zn,As,Pb,Sb and Bi in Copper-Zinc Alloy by ICP-AES

采用ICP-AES同时测定铜-锌合金中锌、砷、铅、锑和铋含量,优化了样品溶样条件。方法检出限为0.0003%—0.0012%,回收率为86%—112%,RSD为0.30%—5.17%,测试结果表明,该方法是测定铜锌合金的简单准确快速的方法。

The content of Zn,As,Pb,Sb and Bi in copper-zinc alloy were simultaneously determined by ICP-AES.The optimum conditions for sample dissolution were performed.The detection limit of the method was 0.0003%—0.0012%.The recovery was 86%—112%,and the RSD was 0.30%—5.17%.The method is simple,rapid and accurate.
