| Abstract: | Electroconductivities of heterogeneous ion-exchange membranes MK-40 and MA-41I are studied experimentally by a band method
in solutions of amino acids with various isoelectric points. Based on the data obtained, three possible mechanisms of electrotransport
in a system membrane-amino acid solution are considered: the charge transfer by hydrogen (hydroxyl) ions, amino acid ions,
and simultaneously by inorganic and amino acid ions (mixed mechanism). |
