负载碳粉富集光谱测定痕量Au、Pd、Pt、Rh

Separation and Spectrometric Determination of Au,Pd,Pt,Rh by Carbon Powder Loaded with Complexant

本文在SnCl_2存在下,用负载二苯基硫脲的碳粉来富集痕量Au(Ⅲ)、Pt(Ⅳ)、Pd(Ⅱ)、Rh(Ⅲ)。然后用其中碳粉作缓冲剂进行矿石中这些贵金属的测定。方法简便,测定结果符合光谱分析要求。

In this paper.a spectrometric method for simultaneous determination of Au, Pd, Pt, Rh after separation by carbon powder loaded with diphenyl thiourea is represented.The optimum conditions for separation were investigated. The ore containing Au,Pd?Pt?Rh was analysed with acceptable recovery.
