摘　　要：用ICP-AES测定镧铜中间合金中的镧,试验研究了分析谱线、试液介质及酸度的选择,基体干扰及其消除。方法简便准确,加标回收率在98.7%—101.6%之间,相对标准偏差<1%,能满足快速检测要求。Lanthanum in La-Cu alloy was determined by ICP-AES. The selections of the analytical line,determination medium,its acid concentration and the matrix interference were studied. The addition recovery is between 98.7%-101.6% and the relative standard deviation is less than 1%. This method is simple,rapid and accurate.
