Electrodialysis is a promising technology to remove low concentrations of target ions from multi-ionic mixtures. While the synthesis selective membranes prominent topic in research, few studies have been presented on selectivity-enhancing process design. This work investigates limiting current density as selectivity promoter removing dilute concentrated solution. Ambiguities and challenges prevailing definitions are identified, new approach based Nernst equation proposed, boundary-layer method. Chloride fluoride with starting 10 mM were removed 1 M sodium sulfate base electrolyte varying levels around value. Removal rates, separation efficiencies, energy consumption compared. The efficiencies between chloride had their highest values at 0.93 0.81, respectively, when operating 130 A/m2. We demonstrate that increasing ion through ion-specific possible only requires standard current-voltage data. experimental results suggest optimization an essential supplement membrane development enhance removal by electrodialysis.
