Centrifugal extraction machine adopts acid feed the single solvent extraction process, do the following improvement: in order to ensure that the yield of thorium, with 30% of the TBP extraction of thorium and uranium, near the water phase export ( Away from the water phase 3 - for export Level 4) Add 13 mol/L HNO3 as salting-out agent; In order to improve the lobes of the nuclide Ru decontamination, material liquid to join hydrazine preprocessing. With 0. 3 mol/L hydrazine hydrate under 95 oc processing material liquid 3 h of ruthenium decontamination factor can be increased 30 - 40 times; In order to improve the efficiency of extraction of uranium, in the process of using centrifugal extraction machine increased the proportion of the extraction liquid, the uranium organic phase/reverse extraction liquid = 9/5. The experimental results show that after centrifugal extraction machine adopts acid feed of single solvent extraction process to extract, uranium, spit yield reached 99. 5% and 99. 8%.
