KINETICS OF EXTRACTION AND STRIPPING OF COPPER WITH ANTI 2-HYDROXY-5-NONYLBENZ0PHENONE OXIME

Abstract

Kinetic studies of extraction of copper with anti 2-hydroxy-5-nonylbenzophenone oxime and stripping of copper were carried out in a stirred transfer cell, along with studies of extraction equilibrium of copper with the extractant and adsorption equilibria of the extractant and the copper chelate complex between the organic and aqueous solutions at 303 K. The extraction and stripping rates were analyzed by an inter-facial reaction model between the adsorbed extractant and the adsorbed 1:1 copper chelate complex accompanied with the mass transfer rates of the species. Furthermore, the extraction rate was simulated by using the equilibrium and reaction rate constants obtained from the analysis.
