Specific surface reactions have been studied by adsorbing different type of substances on the surfaces of kaolinite and gamma-alumina. Analyses were performed by means of FT-Raman and diffuse reflectance mid-IR. The DRIFT spectra indicate isotopic exchange of hydroxyl groups on kaolinite and that it is possible to adsorb silanes at the surface. DRIFT and FT-Raman spectra indicate that the solvent map react with the gamma-alumina surface and that phosphate adsorption occurs at the surface.
