原子荧光光谱法测定铜矿中硒和碲

Determination of Selenium and Tellurium in Copper Ores by Atomic Fluorescence Spectrometry

摘要: 介绍了铜矿中Ｓｅ，Ｔｅ的测定方法，样品经ＨＮＯ３－ＨＣｌＯ４分解，以含ＨＣｌＯ４的０．２ｍｏｌ／ＬＨＣｌ溶液通过７４３型阳离子树脂分离Ｃｕ，原子荧光光谱法测定Ｓｅ，Ｔｅ。

Abstract: The copper ore samples are dissolved in HNO3-HC1O4 and the copper is removed by cation exchange resin No. 743 from 0. 2mol/L HC1. Se and Te are determined by AFS. 6~8 mg Cu causes no interference in this rapid and simple method.
