Some features of the non-exchane sorption of amino acids’s mixtures and 2-1 charge salts by low basic anion exchangers

Abstract

Non-exchange sorption regularities of amino acids mixtures such as "phenylalanine-calcium
chloride", "glycine-calcium chloride" by low basic anion exchangers in Cl-form were investigated. It was
revealed that calcium chloride was absorbed in all concentration range, phenylalanine and glycine were
conversely remained in solution. It was established that the nature of lateral radical doesn't impact on an
interphase equilibrium and a protolytic equilibrium in these sorption systems. These equilibriums are
determined by means the presence of aminocarboxylic group in amino acids structure.
