Selective sorption of binary mixtures has been studied on bentonite and organophilic bentonite. Adsorption excess isotherms on these adsorbents have been determined for benzenen-n-heptane and alcohol-benzene mixtures, and the adsorption capacity of the components has been calculated by the analysis of the excess isotherms. The organocomplex swells only to a small extent in benzene-n-heptane mixtures, while in alcohol-benzene mixtures significant swelling and disaggregation occurs owing to positive adsorption of the alcohols. The results of adsorption measurements are concordant with the swelling and disaggregation characterized by sediment volume measurements.
