- Abstract
The work is aimed at studying electrochemical behavior of ion-exchange membranes in order to optimize the electrodialysis desalination of amino acid solution. The current–voltage and transport characteristics of ion-exchange membranes MA-40, MA-41, and MC-40 in electrodialysis demineralization of tyrosine or phenylalanine solutions containing also one of the mineral salts such as NaCl, NaBr, and KCl have been researched. The influence of the mineral salt ion nature (ion radius and mobility, hydration shell kind) and membrane functional groups on the amino acid and mineral ion fluxes through the membrane at the overlimiting currents has been revealed.
