IRIS(CID)-ICP-AES法同时测定炼锑中Pb、Fe、Cu、As、Bi、Hg和Se的含量

A Method of Simultaneous Determination of Pb,Cu,As,Bi,Hg, Fe and Se in Antimony Ingot by IRIS(CID) ICP AES

本文使用美国ＴｈｅｒｍｏＪａｒｒａｌＡｓｈ公司先进的ＩＲＩＳ（ＣＩＤ）全谱直读等离子体光谱仪，用络合酸溶的方法，直接测定炼锑中Ｐｂ、Ｆｅ、Ｃｕ、Ａｓ、Ｂｉ、Ｈｇ和Ｓｅ的含量，方法有较好的检出限，加标回收试验结果表明，回收率在９８％－１０２％之间。ＲＳＤ＜２％。

In this paper,a method is studied for simultaneous determination of Pb,Fe,Cu,As,Hg,Bi and Se in antimony ingot by using Thermo Jarrell Ash corporation′s advantaged IRIS(CID) plasma spectrometer.The samples were prepared by the methods of complex acid solution.And then were determined directly without seperating matrix element antimony.The method has good detection limit.By the method of add standards testing, the results show that the rate of recovery is 98%-102%.The relative standard deviation is less than 2%.
