摘要
本文采用火焰原子吸收法对碳酸镉中的K、Na、Ca、Mg、Pb、Zn和Fe 7种杂质元素进行测定,方法简单、快速、干扰小,具有较高的准确性和精密度。各元素的相对标准偏差为:2.69％～6.38％,加标回收率为95.0％～105％。
The determination of K,Na,Ca,Mg,Pb,Zn and Fe in Cadmium carbonate by Flame Atomic Absorption Spec-trometry was developed in this paper. The interferences and corrections of coexist elements were discussed. The method was simple, rapid and accuracy .The recoveries of K,Na,Ca,Mg,Pb,Zn and Fe were between 95.0% and 105% . The relative standard deviation were between 2.69% and 6.38% .
