4,4′—壬二酰基—双(1—苯基—3—甲基—5—吡唑酮)与磷酸三丁酯对铀(Ⅵ)的协同萃取的研究

Study on Synergic Extraction of Uranium (Ⅵ ) with 4, 4'-Nonanedioyl-Bis (1-Phenyl-3-M ethyl-5-Pyrazolone) (H_2A) and Tributyl Phosphate (TBP)

研究了4,4′-壬二酰基-双(1-苯基-3-甲基-5-吡唑酮)(H_2A)与磷酸三丁酯(TBP)对铀(Ⅵ)的协同萃取行为,用斜率法测定了协萃合物的组成为UO_2A·TBP,求得协萃平衡常数logK_(se)为1.49,推测了协萃合物的可能结构。

In this paper, the synergic extraction behavious of uranium (Ⅵ) with H2A and TBP have been studied. The composion of the synergic extracting complex UO2A · TBP has been comfirmed by the slope method. The synergic extracting equilibrium constant (logKse) is 1.49. The probable structure has been discussed.
