Title: Kinetic and thermodynamic separation of Cu(II) and Fe(III) by liquid-liquid extraction with a. beta. -hydroxy-oxime in toluene

Abstract

A quantitative study of the thermodynamic and kinetic separation of Cu(III) and Fe(III) by liquid-liquid extraction with toluene solutions of the oxime 2-hydroxy-5-t-octyl(acetophenone oxime) has been conducted. On the basis of the stoichiometry, equilibrium constants, rate laws and rate constants of the extraction reactions of Cu(II) and Fe(III) an equation has been derived which describes how the separation of Cu from Fe varies with the chemical composition of the system, the hydrodynamics of the extracting apparatus and the contact time between the aqueous and the organic phases. Our results show that separations which are not feasible thermodynamically are possible when the contact time between the two phases is kept much shorter than that required to reach equilibrium. 4 figures.
