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