Limiting current densities in a system with cation-exchange membrane MK-100 rotating in a glycine-HCl solution

Limiting diffusion current densities in an electromembrane system (EMS) com prising cation-exchange membrane MK-100 and a glycine solution containing h ydrochloric acid are studied on a rotating membrane disk. The dependence of the limiting current density at a given rotation rate of the disk on the e quilibrium volume concentrations of glycine cations and protons in solution is described by a regression model. The diffusion fluxes of these cations in the EMS are shown to be independent.
