流动注射在线清理MPT-AES测定钯、铂和金的研究

Determination of Pd,Pt and Au by Microwave Plasma Torch Atomic Emission Spectrometry Using an On-line Clean-up

本文研究了在大量Li+、Na+、K+、Ca2 +和Mg2 +离子存在时 ,通过在线清理用微波等离子体炬原子发射光谱法 (MPT AES)测定Pd、Pt和Au三种元素的可能性。实验结果表明 ,样品溶液通过阳离子交换树脂柱后 ,这些离子的干扰基本消除了。将所建立的方法用于一些实际样品分析 ,得到的结果满意。

In this paper,in the presence of Li+,Na+,K+,Ca2+ and Mg2+, determinations of Pd,Pt and Au by microwave plasma torch atomic emission spectrometry (MPT-AES) using an on-line clean-up were studied. It was shown from the experiments that these interfering matrix elements might be removed with the strong acidic cation exchange resin. The method was applied to the analysis of some practical samples and the results obtained were satisfactory.
