摘要
本文介绍化学光谱法测定Ｕ_３Ｓｉ_２中１７种杂质元素。用ＴＢＰ作固定相，采用柱上萃取色层法分离铀与杂质元素，铯为外加基体，铟为内标。平均回收率在８８％—１１５％之间，相对标准偏差优于１３％。
This paper introduces a determination of 17 impurity elements in U3Si2 by chemical spectrum.With TBP as locking phase,impurity elements are separated in uranium by column extraction chromatography,the external matrix is cesium and the internal standard is indium,The recoveries are 88% to 115%,and the relative standard deviations are with in 13% for the different impurity elements
