  4. Back extraction by hno3 - hf and back extraction by concentrated hnch after lower the concentration of organic phase are studied, the method of back extration by hnorhf can not be used to icp - ms, because some zirconium is hydrolysis when hf is removed by heat. however, the method of back extraction by concentrated nitric acid after lower the concentration of organic phase can be used to icp - ms, the recovery is 93. 2 %, rsd % is 5. 24 %, the decontamination factor of uranium is 3. 2xl04, the detection limit of zirconium is 0. 04ng / ml. the method of tta extracting trace zirconium in uranium is firstly used to icp - ms, the result is satisfied, it can be used to determine zirconium in uranic production quickly and veraciously

    本文通過研究hno _ 3 - hf反萃和稀釋有機相後用濃hno _ 3反萃這兩種分離方法，認為hno _ 3 - hf反萃由於在加熱去除hf時酸度不易控制，導致鋯的部分水解，因而此方法不宜用於icp - ms中，然而稀釋有機相後用濃hno _ 3反萃法用於icp - ms測量中，全程回收率為93 . 2 ，相對標準偏差為5 . 24 ，鈾的一次去污因子為3 . 2 10 ~ 4 ，鋯的測定下限為0 . 04ng / ml ，本文首次將tta萃取分離鈾中鋯用於icp - ms測量中，結果令人滿意，此方法適用於快速、準確測量鈾產品中微量鋯。
