The results of the study indicated the significant adsorption interaction of the components in the adsorAdsorption phenomena accompany many industrial processes, determining their contribution to the overall state of a real physicochemical system. Up to now, adsorption on porous polymer sorbents, in particular during ultrafiltration of curd whey, has been inadequately studied since the role of adsorption processes is considered insignificant. In addition, the problem of a comprehensive study of adsorption equilibria is difficult due to the complexity of the intermolecular interactions of the multicomponent mixtures.One of the most important problems in adsorption theory is to develop methods for the experimental and theoretical investigation of adsorption equilibria in binary and muiticomponent systems.Thermodynamic adsorption theory is based on the correlation of the experimental adsorption value with the thermodynamic functions of the system as a whole. It can be used to characterize adsorbate--adsorbate and adsorbate--adsorbent interactions.The following topics were considered in our article: -analysis of the adsorption isotherms of the low-molecular-weight components of curd whey on cellulose diacetate membranes; -calculation of the thermodynamic functions of the adsorption system; -determination of the character of the adsorbate--adsorbate and adsorbate--adsorbent interaction.
