Popis:	Abslmct Sobent extraction of Copper (11) using I-Phenyl-3-methyla-nitrobenzoyl-5pyrazolone (HNPZ) in various organicsolvents has been studied. The extractablespecies has been identified by investigation of log-log plot of distribution ratios and reagent concentrations. Job's method and mole ratiomethd confirmed the mole ratio Cu:HNPZ to be 1:2. Maximum and reproducible results were obtained a?pH 4-6, and equilibration wasachieved within fewseconds. Wealso observed that thecapacity of the organicloading wassignificantly higherwhen chlorofoim and benzene were used assolvents. Equilibrium extraction constant, log Kex, yas detennined from experimental data as - 1.60.
