摘要
提出了运用FAAS法连续分析测试电池锌粉中Mg、Fe、Cu、Pb、Mn的含量,给出了Mg、Fe、Cu、Pb、Mn最佳测定条件及线性范围,在测定中对样品中的干扰因素进行了综合考虑.方法具有很好的灵敏度和重现性,步骤简单、操作容易、干扰少.测定样品Mg、Fe、Cu、Pb、Mn含量的相对标准偏差均小于1.0%（n=10）.标准加入回收率均在97.0%-101.5%（n=6）范围内.适用于电池锌粉中Mg、Fe、Cu、Pb、Mn的含量控制分析和样品系统分析.
The continuous determination of magnesium、iron、copper、lead and manganese in zinc powder of battery was carried out by FAAS.The optimal measuring conditions for magnesium、iron、copper、lead and manganese,and liner range were presented.A comprehensive consideration on in terference factors in the determination of samples had been carried out.The method has the advantages of high sensitivity less interference and good selectivity and reproducibility.The RSD is 1.0% comparing to the standard value.The spiked standard recovery was 97.0%～101.5%.The method is applicable for the analysis of controlling the contents of Mg,Fe,Cu,Pb and Mn and also for the systematic analysis of samples.
