摘　　要：本文采用ＪｏｂｉｎＹｖｏｎ３８Ⅱ光谱仪直接测定高纯氧化铕中Ｃｓ、Ｐｒ、Ｓｍ、Ｇａ、Ｄｙ５个稀土杂质，试验考查了氧化铕基体，共存元素，酸度等因素的影响。利用正文试验Ｌ＿（２５）（５）￣６确定了仪器最佳条件。当基体纯度为９９．９９％时；回收率在９４．０～１０８．０％之间。在实际应用中获得满意的结果。The impurities in highly pure europium oxidewere directly determined on Jobin Yvon 38 Ⅱ type e-mission spectrometer.The matrix and minor compo-nent interferences and the efect of the acid concentra-tion were examined.Orthogonal design L_(25)(5)￣6 wasapplied for the optimization of excitation conditions.When the purity of europium oxide was 99.99%, therelative standard deviations were less than 6.5%andthe spiked recoveries were from 94%to 108%, Satis-factory results were obtained in practical applications.
