Adsorption of liquid mixtures on hydrophilic and organophilic kaolinite

Results relating to selective sorption from methanol-benzene mixtures show that methanol is adsorbed preferentially on the original polar kaolinite and that an excess isotherm of type II is obtained. If the surface of the kaolinite is modified by alcohol treatment or is covered to various extents by...

Description
Summary:Results relating to selective sorption from methanol-benzene mixtures show that methanol is adsorbed preferentially on the original polar kaolinite and that an excess isotherm of type II is obtained. If the surface of the kaolinite is modified by alcohol treatment or is covered to various extents by HDP cations, excess isotherms of type IV results. The extent of surface modification can be characterized by the azeotropic composition of adsorption, xf.
