Abstract : Apparatus for the study of equilibrium gas adsorption on solids by both volumetric and gravimetric means is described, including pressure measuring devices which allow measurements with adsorbates having a wide range of volalilities. Adsorption and desorption isotherms of nitrogen at low temperatures are reported on an activated carbon fiber and on a coal-based granular carbon. The adsorption isotherm of dimethyl methylphosphonate, DMMP, on an activated carbon fiber at 25 C in the range of 0-0.8 mm Hg pressure is reported. Methods are described for the chemical characterization of surface oxygen complexes on activated carbon according to functional group. (Author)
