Abstract
The hydration properties of KU-2 x 8 sulfocationite saturated with tyrosine (Tyr)and phenylalanine (Phe) (aromatic amino acids) were studied by IR spe ctroscopy and thermal analysis. An increase in the amount of a sorbed zwitt erlyte leads to an increase in the degree of sorbent dehydration, free Gibb s energy, and pressure of swelling. This effect is equivalent to an increas e in the degree of crosslinking of the cationite.
