本文研究了 HPMBP 与 N_(1923)的氯仿溶液从硝酸介质中协同萃取钯(Ⅱ)的机理.用斜率法、等摩尔系列法确定协萃配合物的组成为 RNH_3Pd(PMBP)_3,反应式为:Pd_((a))~(2+)+3HPMBP_((o))+RNH_3NO_(3(o))RNH_3Pd(PMBP)_(3(o))+3H_((a))~++NO_(3(a))~-求得该协萃反应的平衡常数及协萃配合物的生成常数分别为:1gK_(12)=1.77,1gβ_(12)=2.63.
In this paper, the mechanism of synergistic extraction of palladium (Ⅱ) from nitric acid by HPMBP and N_ (1923) in chloroform was studied.The composition of the complex was determined to be RNH_3Pd (PMBP) _3 by the slope method and the equimolar series method.The reaction equation : Pd _ ((a)) ~ (2 +) + 3HPMBP _ ((o)) + RNH_3NO_ (3 (o)) RNH_3Pd (PMBP) 3 (a)) ~ - The equilibrium constants and the formation constants of the coprecipitation complex were determined as follows: 1gK 12 = 1.77,1gβ 12 = 2.63.
