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。 -
It can determine the elements in water. when tta is used to extract zirconium in uranium, the combination of zirconium and tta is very strong, the concentrated acid of nitric acid and hydrochloric acid can not destroy their combination
用tta萃取分離鈾、鋯時， tta對鋯的螯合作用很強，硝酸和鹽酸的濃酸溶液並不能破壞它們之間的整合，即對鋯的反萃取非常困難。 -
A quantitative appraisal of the prospect of uranium mineralization is completed based on a set of hydrochemical data acquired from the known in - situ leachable sandstone - type uranium, including radon content, acid - alkali ratio, oxidized and reduced electronic potential, hydrocarbonate radical and uranium content in water
但是在找鈾過程中僅用水化學成份、氡含量、酸堿度和氧化還原電位等數值進行描述，說明它們與鈾礦化的關系，這種單一因素的描述不能綜合反映與鈾礦化的聯系程度，以定量評價鈾礦化與上述因素的關系，從而影響了水化學找礦的效果。 -
