This paper deals with understanding the surface behaviors of calcined clay and the organic/inorganic system. The surface properties like the adsorption thermodynamic parameters and the dispersive component of the surface energy were determined by the adsorption of n ‐alkanes on the solids that were the subject of interest, i.e. calcined sepiolite and polystyrene coated calcined sepiolite. Inverse gas chromatography (IGC) was used for this purpose. The dispersive component of the surface energy of system lies between the members of system. Additionally Diffuse Reflectance Infrared Fourier Transform (DRIFT) technique was used to record the functional groups of solids. Copyright © 2010 John Wiley & Sons, Ltd.
