摘　　要：铑派克废液中因含有机物、磷和盐类,会影响其含量铑量的准确分析、测定。经对比试验采用火试金法进行样品前处理,火试金熔炼富集过程中添加含铑量3倍的铂和1倍的金富集铑,铑合金粒的密闭溶解;得到的试液采用ICP-AES测定。对含铑量为50~2000 g/t的样品,测定相对标准偏差(RSD)<2%,加标回收率为96.7%~101.3%,满足生产分析要求。Rhodium parker waste liquid contains organic matter,phosphorus and salts,will affect the accurate analysis and determination of rhodium content.Through the comparison test,the sample is pre-treated by fire assay method.In the process of smelting and enrichment of fire assay,platinum with 3 times rhodium content and gold with 1 times l rhodium content are added to enrich rhodium,and rhodium alloy particles are sealed and dissolved.The test solution was determined by ICP-AES.The relative standard deviation(RSD)of the samples with rhodium content ranging from 50 g/t to 2000 g/t was less than 2%,and the spiked recoveries are 96.7%~101.3%,which could meet the requirements of production analysis.
