The selective adsorption properties of the clay minerals montmorillonite and kaolinite and their organophilic derivatives were studied, for alcoholbenzene mixtures. Adsorption excess isotherms were determined, and the adsorption capacities were calculated by the method of Schay-Nagy. It was found that the desaggregation of the clay minerals and their organophilic derivatives can be characterized quantitatively by the adsorption capacity. It could be shown how the shapes of the excess isotherms are affected by modification of the surfaces, and, in this connection, a new model isotherm equation was introduced.
