摘　　要：用微量量热法研究了HPMBP从硝酸介质中对Ag(Ⅰ)的萃取,得到了热功率-时间曲线,确定了298K时此萃取过程的热效应,求出了不同温度下的热力学参数。The solvent extraction of Ag(Ⅰ)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 Ag(PMBP) by the slope analysis met the equilibrium equation of solvent action was concluded as Ag++HPMBP(O)=Ag(PMBP)+H+; and the equation of the action has been obtained as well.
