摘要
介绍了铜矿中Se、Te的测定方法。样品经HNO_3-HClO_4分解,以含HClO_4的0.2mol/L HCl溶液通过743型阳离子交换树脂分离Cu,原子荧光光谱法测定Se、Te。
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.
