摘要
The enthalpies of interaction of polyvinylbenzyltrimethylammonium (PVTA) hydroxide with glycine, glutamic acid, and tyrosine anions were determined calorimetrically. The interaction of PVTA with amino acid anions was shown to be an exothermic process. The enthalpy of interaction depended on the nature and concentration of the amino acid. The reaction became less exothermic and the time of the establishment of equilibrium increased as the concentration of amino acids grew.
