4,4’-癸二酰-双-(1-苯基-3-甲基-5-吡唑啉酮)和TBP对铀(Ⅵ)的协同萃取

SYNERGISTIC EXTRACTION OF URANIUM(Ⅵ) WITH 4,4'-DECANEDIOYL-BlS-(l-PHENYL-3-METHYL -5-PYRAZOLONE) IN THE PRESENCE OF TBP

摘要: <正> 我们已报道了4,4′-癸二酰-双-(1-苯基-3-甲基-5-吡唑啉酮)(以下简写为H_2A)对UO_2~(2+)的萃取作用。用斜率法得到在溶液中萃合物的组成为UO_2A,对离析的固体萃合物的研究表明,其配位结构如图1。

Abstract: In the presence of TBP, synergism has been established as UO22+ is extracted by 4,4'-decanedioyl-bis- (1-phenyl-3-methyl-5-pyrazolone) . Using slope method, the mechanism of synergistic extraction and the constitusnt of extracted complex are studied. The structure of this coordination compound is proposed.
