The first phase of selecting a model binary system to study was completed. The system selected is Cu(II), Fe(III) acid sulfate solutions extracted by ..beta..-alkenyl 8-hydroxy quinoline (Kelex 100) in xylene. Maximum copper extraction occurs in less than 5 minutes at 30 to 50/sup 0/C. Thermodynamic chemical equilibrium studies with the Fe(III) ion indicate that the ionic charge of the extracted ion is +3 over a limited pH and concentration range. A simplified equilibrium model did not fit the experimental data. A chemical equilibrium model for the aqueous phase was developed. Kinetic studies on the liquid jet recycle reactor are underway. The model proposed to analyze simultaneous extraction of Cu(II) and Fe(III) in a stirred tank extractor was reduced to a set of two nonlinear algebraic equations for idealized kinetic expressions.
