ADSORPTION - DESORPTION PROPERTIES OF SORBENTS.
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)
