摘　　要：确定了用电感耦合等离子体发射光谱法直接测定金属铟中的铅铁铜锌镉铝锡钛铊砷10种元素的含量．试验中优化出各元素的分析波长和分析条件，采用基体匹配补偿基体效应．该法操作简单，分析快速可靠，回收率为90％～110％，相对标准偏差为2．1％～12．5％．In this paper, direct determination of Pb, Cd, Fe, Cu, Zn, Al, Sn, Ti, Tl and As in indium with ICP-AES is presented, the operational paraments are optimized, and the interference from matrix is eliminated with matrix matching. The satisfactory results are obtained with this simple and effective method. The recoveries are in the range of 90% to 110% and the relative standard deviations （RSD） are 2.1%.
