KINETIC-STUDIES OF EXTRACTION AND STRIPPING OF COPPER WITH DIBENZOYLMETHANE

Kinetic studies of the extraction of copper with dibenzoylmethane and the stripping of copper were carried out in a stirred transfer cell, along with a study of the extraction equilibrium of copper with the extractant at 303 K. The extraction and stripping rates were analyzed by a model of the interfacial reaction between the extractant and the adsorbed 1:1 copper chelate complex accompanied by the mass transfer steps of the species. Furthermore, the extraction rate was simulated by using the equilibrium and reaction rate constants obtained from the analysis. © 1990, Taylor & Francis Group, LLC. All rights reserved.
