摘　　要：报道了化学光谱法测定５Ｎ高纯氧化钆中１４个稀土杂质元素，在Ｐ５０７萃淋树脂色层柱上分离氧化钆中稀土杂质元素，分别采用定量分离Ｌａ－Ｓｍ及Ｔｂ－Ｌｕ＋Ｙ和部份分离Ｅｕ的方法，并相应地采用碳粉吸附法和碳粉粉末法进行光谱测定。分离时间为３．５ｈ，测定下限为１．２μｇ／ｇ（ＲＥ）。A spectrographic method was developed for the determination of 14 rare earth impurities followed by chromatographic separation with P 507 resin.The optimum conditions for separation and determination were carefully selected.The separation period was comparatively short(3.5h) ,and the determination limit was as low as 1.2μg/g(RE).The method was proposed to analyse 14 rare earth impurities in 5N gadolinlium oxide.
