摘　　要：本文研究了1一苯基一3一甲基一4一乙酰基吡唑啉酮一5（PMAP或HA）、2一噻吩甲酰三氟内酮（TTA或HA`）、1一苯基一3一甲基一4一苯甲酰基吡唑啉酮一5（PMBP或HA"）和甲基膦酸二（1一甲庚）酯（DMHMP或B）四元萃取剂的甲苯溶液，从高氯酸钠底液中对Lu（Ⅲ）的协同萃取，发现有明显的四元协萃效应。用斜率法测得四元协萃络合物的组成为LuAA’A"B，四元协萃平衡常数KAA'A"B=5．7（20℃）。篢he synergistic extraction of Lutecium(Ⅲ) from sodium perchlorate solution withquaternary system of 1 - phenyl - 3 - methyl - 4 - acetyl pyrazolone - 5 (PMAP or HA), 2thenoyl trifluoroacetone (TTA or HA'), 1 - Phenyl - 3 - methyl - 4 - benzoyl pyrazolone - 5(PMBP or HA') and di - (1 - methyl heptyl) methyl phosphonate (DMHMP or B) has beenstudied. The forrnation of a quaternary extracted complex, i. e. LuA'A'B` Was confirmed by theslope analysis method. The equilibrium constant at 20C is determined to be KAA'A'B = 5' 7'
