摘要
通过２羟基５仲辛基二苯甲酮肟（ Ｎ５１０） 与三辛基氧化磷（ＴＯＰＯ） 的氯仿溶液，从高氯酸介质中对钯协同萃取的研究，采用斜率了萃合物的组成为（ＴＯＰＯ）２·Ｐｄ·Ａ－ 协萃反应平衡常数为１ｇ Ｋ１２ ＝ １ ．６６ ，协同萃取配合物生成常数为β１２ ＝ ３－２３ ，同时计算了协萃反应的热力学函数值－
The synergistic extraction of Pd(Ⅱ) from perchloric acid system with 2 hydroxyl 5 sec n octyl diphenyloxme(N 510 ) and TOPO has been investigated. By the method of slope analysis,the compsition of the synergistic extracting complexes have been determined to be (TOPO) 2·Pd·A. The mechanism of the synergistic extraction of Pd(Ⅱ) is proposed as follows: Pd 2+ (A) +H 2A (o) +2TOPO (o) =K 12 (TOPO) 2·Pd·A (o) +2H + (A) Moreover, the equilibrium constants and the thermodynamic functions of the synergistic reactions have been calculated.
