本文研究了1-苯基-3-甲基-4-苯甲酰基吡唑酮-(5)与中性磷萃取剂磷酸三丁酯(TBP),甲基瞵酸二异戊酯(DIAMP),丁基膦酸二丁酯(DBBP)和三丁基氧化膦(TBPO)的苯溶液从硝酸介质中对铀(Ⅵ)、铈(Ⅲ)、钙(Ⅱ)的萃取,发现均有程度不同的协同效应.测定了协萃络合物组成为UO2X2·B(其中B为TBP,DIAMP,DBBP,TBPO),CeX3·2B(B为DIAMP,DBBP,TBPO)和CaX2·2TBPO.分别计算了它们的萃取平衡常数.简单讨论了协同效应的机理与中性磷萃取剂的Lewis碱性的关系.

The extraction of uranium(Ⅵ),cerium(Ⅲ),and calcium(Ⅱ) from nitric acid into miB.tures of 1-phenyl-3-methyl-4-benzoyl-pyrazolone-(6)(PMBP),and a neutral organop hosphorus extractants,e.g.tri-n-buty 1 phosphate(TBP),di-iso-amyl methyl phosphonate(DIAMP),di-butyl butylphosphonate(DBBP) or tri-n-butyl phosphino oxide(TBPO) in benzene has been studied.The extraction coefficients have been found to be greater for suoh mixtures than for either component alone.
