The authors construct a mathematical model for electrodialysis and solvent extraction via an ion-selective ion exchange membrane and accounts for the electrochemical, ion exchange, and diffusional behavior of the processes including their dependence on component concentration and current and voltage. The model is tested against experimental data for the electrodialytic transport of anionic platinum complexes of chlorides from hydrochloric acid solution through tributylphosphate membranes. The platinum concentration in the aqueous solution was determined by gamma spectroscopy obtained via platinum 191 as a radiotracer.
