研究了2-羟基-4-仲辛基-二苯甲酮肟在氯仿中萃取钯的行为及2-羟基-4-仲辛基-二苯甲酮肟与三辛基氧化膦协同萃取钯的行为。用斜率法确定了萃合物组成为PdL和PdL(TOPO)2。同时了计算平衡常数及热力学参数。实验结果表明,升高温度对2-羟基-4-仲辛基-二苯甲酮肟萃取钯及2-羟基-4-仲辛基-二苯甲酮肟与三辛基氧化膦协同萃取钯有利。 The extraction behavior of 2-hydroxy-4-sec-octyl-benzophenone oxime in chloroform and the synergistic extraction of palladium with 2-hydroxy-4-sec-octylbenzophenone oxime and trioctylphosphine oxide behavior. Slope method was used to determine the composition of PdL and PdL (TOPO) 2. At the same time, the equilibrium constants and thermodynamic parameters were calculated. The experimental results show that the synergistic extraction of palladium with 2-hydroxy-4-sec-octyl-benzophenone oxime and the co-extraction of palladium with 2-hydroxy-4-secoctyl-benzophenone oxime and trioctylphosphine oxide favorable.
