用DTPA配位反萃镎实验进行了分离铀镎的串级实验研究。实验结果表明，在所选定的实验条件下，铀中镎的去污因子都大于10。铀的回收率由于补萃液TBP酸度和补萃级数不同而不同。在三级补萃、补萃液酸度为0.6 mol/L时，铀的回收率可达98.3 %。 Cascade experiments on the separation of uranium from DTPA coordination stripping experiments were carried out. The experimental results show that under the selected experimental conditions, the decontamination factor of uranium 镎 is greater than 10. The recovery of uranium will vary depending on the TBP acidity of the stripping solution and the number of stripping stages. In the third-level make-up, make-up liquid acidity of 0.6 mol / L, uranium recovery rate of up to 98.3%.
