Abstract—The electrical mass transfer of cations in electromembrane systems (EMS) with an MK-40 cation-
exchange membrane and glycine in aqueous solutions of hydrochloric acid is studied using the method of a
rotating membrane disk. Limiting current densities and limiting steps of the transport of cations in such systems
are determined. Shown is the possibility of an increase in the electrical mass transfer of glycine as a conse-
quence of the occurrence of a heterogeneous reaction of protonation of its zwitterions. The effect of the mem-
brane surface state on the kinetic regularities of transport of cations in EMS with glycine in solutions of hydro-
chloric acid is exposed.
