ICP-AES法测定铅锌混合矿中的铁、铜、砷、锌、镉、汞

The Determination Of Fe,Cu,As,Zn,Cd,Hg in Pb-Zn Ore With ICPAES Method.

采用ICP-AES同时测定铅锌混合矿中铁、铜、砷、锌、镉、汞六种元素的含量,优化了实验条件,各元素的检出限为0.0069-0.07ug/m L,相对标准偏差为0.3%-4.72%,样品加标回收率为85.5%-112.8%。测试结果表明,该法测定铅锌矿的简单、准确、快速。

Contents of elements（Fe,Cu,As,Zn,Cd,Hg ）in Pb-Zn ore were determined by ICP—AES.The detection limts of various elements were from0.0069ug / mL to 0.07ug / mL,RSDs were between 0.3 % and 4.72 %, and recoveries were in the range of 85.5%-112.8%.The results show that the method is simple,rapid and accurate,and can be applied to determination of Pb-Zn ore.
