Chromatographic Silica Gel: Surface Area Determined by Adsorption

Chromatographic Silica Gel: Surface Area Determined by Adsorption

The surface area of silicic acid, a form of silica gel, has been determined by adsorption of methanol from a benzene solvent. The method is straightforward, uses inexpensive apparatus, and should be applicable to other particulate adsorbents.
