摘　　要：采用硝酸-高氯酸分解试样,ICP-AES法同时测定铅、铜和铁。建立了一个准确、快速、简便的测定方法,适用于新制和失效钯炭中铅、铜和铁量的测定。Pb、Cu、Fe测定范围为0.01%-0.1%;方法的加标回收率为95.8%-100.9%;相对标准偏差RSD〈5%。A simple accurate and precise analytical method for the determination of lead, copper and iron in palladium-carbon catalysts by ICP-AES was proposed. The digestion of sample which contains lead, copper and iron in the range between 0.01%-0.1% in fresh or spent palladium-carbon, was obtained using both HNO3 and HClO4. The recoveries were ranged from 95.8% to 100.9%. The precision, expressed as relative standard deviation （RSD） of the method, is better than 5%.
