摘　　要：为了测定铀矿石浓缩物中杂质元素的含量,需要将基体铀与杂质元素进行分离。本文主要讨论了用TBPCCl4萃取分离除去大量铀以后应用TBP微色谱柱进行微量铀与杂质元素的分离。用ICP-AES测定流出液中部分杂质元素的含量,发现优化后的方法可以使待测杂质元素与铀达到完全分离,并能定量回收,结果令人满意。In order to determine the content of impurity element in uranium ore concentrate,need to separation of uranium and impurity elements. This paper mainly discussed application of the TBP micro chromatographic column to separation of uranium and impurity elements after extraction separation to remove uranium use the TBP-CCl4. Determination the content of part of the impurity elements in the effluent use ICP-AES,found that the optimized method can make to achieve complete separation of uranium and impurity element,and can quantitatively recycling,the result is satisfactory.
