ICP-AES法直接测定精镉中铅、锌、铁等八种杂质元素

The 8 Kinds of Impurity Elements of Pb,Zn,Fe Etc.in Refined Cadmium Are Directly Measured by ICP-AES Method

本文采用电感耦合等离子体全谱发射光谱仪直接测定精镉中Pb、Zn、Fe、Cu、TI、As、Sb,SnO研究了分析线。的选择，酸度条件和基体干扰情况。该方法的相对标准偏差为1．60％-5．96％，样品加标回收率为93％～105％，简便、快速，测定结果令人满意。

The paper has used to directly measure Pb,Zn,Fe,Cu,TI, As,Sb and Sn in refined Cadmium （Cd） by IRIS Advantage. And selection of analysis line, conditons of acidness and interference situations of main sampling mattters has been studied in the paper. The relative standard deviation of the measuring method is in the range of 1.60% - 5.96%. The measuring methods are simple, quick and the results has been satisfied with us.
