title: Description of multicomponent adsorption and absorption phenomena from a single viewpoint.
abstract: On the basis of phenomenological thermodynamics, an equation has been derived that represents one of the interphase equilibrium equations and provides a description of both multicomponent adsorption and absorption phenomena from a single point of view. The approach is based on a free-volume state equation for the adsorbed phase. It is shown that the well-known Henry, Langmuir, Fowler-Guggenheim, Temkin, and BET adsorption equations (generalized for gas mixtures) follow directly from the equation proposed with constants having a clear physical meaning.
