INTERACTION OF PHENYLALANINE AND HISTIDINE ON EQUILIBRIUM CHARACTERISTICS OF ADSORPTION OF AMINO ACIDS ON CLINOPTILOLITE

Parameters of the equilibrium sorption of phenylalanine and histidine on clinoptilolite from aqueous solutions containing the individual amino acids and their mixtures were presented. The contribu-tion of exchange and non-exchange components in the adsorption capacity of clinoptilolite was deter-mined. It was found that the interfacial distribution of amino acids is determined by the ratio of CHis / CPhe and manifested in sorption equilibrium characteristics. The maximum degree of extraction of histi-dine is achieved at the ratio of CHis / CPhe equals to 1: 3.
Key words: clinoptilolite, sorption, aminoacids
