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 contribution of exchange and non-exchange components in the adsorption capacity of clinoptilolite was determined. 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 histidine is achieved at the ratio of CHis / CPhe equals to 1: 3.
