The swelling, moisture sorption, particle size, cation-exchange, and drug adsorption properties of selected montmorillonites were studied. The swelling of montmorillonite was found to depend on both adsorptive and osmotic phenomena. The study of the sorption of alkaloidal drugs by the clay showed that brucine was sorbed by both adsorption and ion-exchange reactions, forming a monomolecular layer on the interior surface of the clay; methapyrilene and triethylamine were sorbed by an ion-exchange reaction; and niacinamide was neither adsorbed nor ion-exchanged.
