Abstract

A physicochemical model for the transfer of amino acids through the interface between a cation-exchange membrane and an amino acid aqueous solution is proposed. The model allows for a heterogeneous reaction of protonation of the amino acid zwitterion. The model calculations are compared with experimentally determined migration transport numbers for glycine cations in an electromembrane system with an MK-40 membrane. The comparison shows that, owing to the protonation reaction, the glycine flux can increase by ca. 30%.
