研究了1-苯基-3-甲基-4-苯甲酰基吡唑酮-5(HPMBP)从硝酸介质中对Ag+的萃取,测定了萃取反应的反应热ΔrHmθ;运用斜率法得出萃合物的组成为Ag(PMBP);得到了萃取反应平衡方程式Ag++HPMBP(O)=Ag(PMBP)+H+;得出了反应的速率方程v=Kf[HPMBP](O)[H+][Ag+]-Kb[HPMBP](O)-2[H+]-1[Ag+](O)
The extraction of Ag + from 1-phenyl-3-methyl-4-benzoylpyrazolone-5 (HPMBP) from nitric acid medium was studied and the reaction heat ΔrHmθ was determined. The composition of the material is Ag (PMBP); the equilibrium equation of the extraction reaction is obtained: Ag ++ HPMBP (O) = Ag (PMBP) + H +; the rate equation of the reaction is obtained as v = Kf [HPMBP] Ag +] - Kb [HPMBP] (O) -2 [H +] - 1 [Ag +] (O)
