Thermokinetic Research of the Solvent Extraction of Pb(Ⅱ) with 1-Phenyl-3-Methyl-4-Benzoyl-Pyrazolone-5 in a Nitric Acid Medium
【摘要】 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Pb2+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Pb（PMBP）2;得到了萃取反应平衡方程式Pb2++2HPMBP（o）=Pb（PMBP）2+2H+;得出了反应的速率方程v=Kf[HPMBP]（o）[H+]2[Pb2+]-Kb[HPMBP]（o）-1[H+]-2[Pb2+]（O）.
【Abstract】 The solvent extraction of Pb（Ⅱ）with 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5（HPMBP） from the medium of Nitric Acid was studied,and the composing of complex was obtained as Pb（PMBP）-2 by the slope analysis method;the equilibrium equation of solvent action was concluded as Pb2++2HPMBP-（（o））=Pb（PMBP）-2+2H+;and the rate equation of the action has been obtained as well.
