摘　　要：实验采用铅试金富集得到含有贵金属合粒,经硝酸和盐酸溶解,在王水介质中利用电感耦合等离子发射光谱法(ICP-AES)测定印刷线路板污泥中金、钯的含量。实验结果表明:该方法精密度好、准确度高,金、钯的加标回收率为96.4%~108.0%、相对标准偏差(RSD,N=7)为1.73%~4.05%,可以满足印刷线路板污泥中金、钯的测定。A method based on ICP-AES with lead-assaying enrichment was established to determine Gold and Palladium in printed circuit board(PCB)waste sludge.Gold and Palladium in bead which enriched from lead assay were dissolved with hydrochloric acid and nitric acid,The contents of Gold and Palladium were determined in aqua regia by ICP-AES.The results were showed as follows:Recovery rate of Gold and Palladium ranged from 96.4%to 108.0%and relative standard deviation(N=7)ranged from 1.73%to 4.05%.Good precision and high accuracy of the method can meet the analysis requirement for determination of Gold and Palladium in PCB waste sludge.
