Abstract
A new method of chronopotentiometric study of electroosmotic water transfer in the electromembrane system containing amino acid solution is elaborated. An electrodiffusion problem, which allows for a convective solvent transfer in the system, is formulated and solved. By comparing calculated and experimental transition times for MK-40 and MF-4SK cationite membranes in lysine monohydrochloride solutions, the electroosmotic permeability of the membranes and transport numbers of water through them are calculated. A considerably higher electroosmotic water transport through MK-40 as compared with MF-4SK is attributed to differences in their nature and structure.
