摘要
采用火焰原子吸收光谱法(FAAS)连续分析镉镍电池浸渍用硝酸钴中铜、铁、锰、锌含量,同时对样品中的干扰因素等进行了综合考察。实验结果表明,该方法具有灵敏度和重现性很好、分析步骤简单、操作容易、干扰少等特点。相对标准偏差均小于1.0%,回收率均在97.0%～101.0%之间。该法适用于硝酸钴中铜、铁、锰、锌含量控制分析和样品系统分析。
The contents of Cu, Fe, Mn, and Zn in cobalt nitrate, used for cadmium-nickel cell dipping, were analyzed continuously by flame atomic absorption spectrometry. The interferential factors in the sample were investigated. The results show that the method has the advantages of simplicity, easiness, and less interferences. The RSDs of four elements were less than 1.0%, and the recoveries were in the range of 97. 0% -101.0%.
