The enthalpies of interaction of strongly basic anionites with amino acid ions

The enthalpies of interaction of strongly basic anionites ARA-1p, AV-17-8, and AV-29-12P with glycine, glutamic acid, and tyrosine anions were determined by microcalorimetry. The interaction of ionites with amino acid anions over the selected concentration range was accompanied by heat release. The value and duration of heat release and the enthalpy of the process depended substantially on the structure of the ionite and the amount of the cross-linking agent and the structure, properties, and concentration of amino acids. An attempt was made to consider the influence of the hydrophobic properties of amino acids on the enthalpy of the process.
