摘　　要：轴承用铜钢复合双金属板样品经硝酸、盐酸溶解后,以铑为内标,用电感耦合等离子体原子发射光谱(ICP-AES)仪测定试料溶液中待测元素特征谱线的强度,通过内标标准曲线法计算出试料中镧、铈量,轴承用铜钢复合双金属板1#、2#样品的精密度(RSD)为0.98%～1.1%,加标回收率为97.0%～105%,说明方法准确、可靠。The sample of copper-steel clad plates for bearings was digested in nitric acid and hydrochloric acid,with Rh as internal standard,determined the intensity of characteristic line of elements to be measured in specimen solution by using inductively coupled plasma atomic emission spectrometry(ICP-AES).The contents of La and Ce in specimen were calculated by standard curve method.The precisions of 1^#and 2^#copper-steel clad plates for bearings(RSD)were in the rate of 0.98%-1.1%,and the recoveries rate were between 97.0%and 105%.The results show that the proposed method is accurate and reliable.
