摘　　要：研究了ICP—AES法测定23Co13Ni11Cr3Mo钢中的La，Ce元素的分析方法和基体及共存元素对测定La，Ce的影响，优选了分析线。方法检出限，La398．852nm为0．0079μg／mL；Ce418．660nm为0．0089μg／mL，La，Ce回收率为99％～103％；RSD均小于5％。样品对照分析，本结果与ICP—MS测得的一致，表明方法准确可靠。The determination method of La, Ce in 23Co13Ni11Cr3Mo steel by ICP-AES was studied. The spectral interferences of martrix and coexist elements were studied. And the analytical lines were determined. The limits of La 398. 852nm was 0. 0079μg/mL and Ce 418. 660nm was 0. 0089μg/mL. The rate of recovery is in the range of 99%-103% ,The relatively standard deviation （RSD%） of results are less than 5 % for Ce elements（≤0. 005 %） and for La elements（≤0. 005 %）. The contrast result of the method and ICP-MS method was accordant,It has been proved that the method is accurate, simple and rapid.
