Аннотация:On the basis of a model in which the adsorption solution is treated as the phase having a limited capacity with respect to the system components, a general thermodynamic theory of adsorption has been developed, which enables one, by proceeding from uniform principles, with the same choice of standard states of the components (and, in particular, of the adsorbent) in the phases, to describe equilibria of physical (localized and nonlocalized) adsorption and chemisorption of individual fluids and their mixtures from bulk phases of any aggregate state (gases, vapors, liquids). Within the framework of the method of activities, n mathematical tool of the theory has been developed, applicable to the problems of thermodynamic treatment of experimental data related to the adsorption of one- and two-component fluids on adsorbents of different structure. It is demonstrated that, owing to its general character, this theory may provide the thermodynamic basis for the development of methods of a priori calculation of adsorption equilibria.
