A new description of physical adsorption on microporous solids from binary non-electrolyte solutions with limited miscibility of the components is described. Equations are formulated which are equivalent to the Freundlich and Dubinin–Radushkevich equations; these have been used to describe experimental isotherms of excess adsorption on active carbon from iodine (component 1) solutions in nine organic solvents. It is shown that in every case the adsorbed phase in equilibrium with the saturated solution is essentially free from component 2.
