Abstract

Hydration characteristics of heterogeneous sulfocation-exchange membranes MK-40 and
FTCM-E in hydrogen and amino acid’s forms are studied by IR-spectroscopy. Energy of hydrogen bonds
in ion-exchange membrane is calculated on the basis of absorption strips displacement in the IRspectrum.
Basic amino acids sorption by the membrane leads to a decrease of total water content in the
membrane phase and to an increase of water molecules fraction having high values of hydrogen bonds
energy.
