摘要
在高温高压条件下用盐酸-双氧水消解铑粉样品,采用电感耦合等离子体发射光谱仪(ICP-AES)测定其中16种杂质元素[1].进行了光谱干扰研究、谱线选择、加标回收、精密度以及基体匹配比对试验.该方法简便、快速、准确,其测定范围为0.0005%～0.10%,RSD在1.88%～12.15%之间,加标回收率在92.0%～114.6%之间,不同方法结果对照数据吻合良好.该方法可满足铑粉中16种杂质元素的测定要求.
Abstract
The rhodium powder sample was digested with hydrochloric acid-hydrogen peroxide under high temperature and high pressure conditions,and 16 impurities were determined by inductively coupled plasma emission spectrometer(ICP-AES).Spectral interference studies,spectral line selection,spiking recovery,precision,and matrix matching alignment tests were performed.The method is simple,fast and accurate,with its determination range of 0.0005%～0.10%,RSD between 0.5%and 5.73%,and the spike recovery rate is between 97.0%and 108.1%.The results of different methods are in good agreement.This method can meet the determination requirements of 16 impurity elements in rhodium powder.
