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) comprising cation-exchange membrane MK-100 and a glycine solution containing hydrochloric 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 equilibrium 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.
