In this study, we developed a simulation method for cation transport through cation-exchange membranes in an electrodialysis (ED) system containing 9 kinds of ions (Na+, K+, Mg2+, Ca2+, Sr2+, Cl-, Br-, HCO3-, SO42-) by using ionic mobility derived from the modified Mackie and Meares’ theory. In order to confirm the validity of the simulation, we also conducted ED experiments using standard commercial IEMs. As a result, the measured values and the simulations agreed quantitatively with each other, even in the multi-component ion system. The simulation will help in the prediction of optimal ED operation conditions to reduce the running cost and/or to increase product purity.
