摘要

The surface chemistry of carbon fabric (CF) was modified by both chemical and physical activation. The increasing oxygen concentration was estimated by using elemental analysis, and quantified by temperature programmed decomposition (TPD) in helium atmosphere. Modified carbon fabrics were used as adsorbents during the removal of a model volatile organic compounds (VOCs) isopropanol from gas streams. Typical results indicated that CF modified by air plasma has the best adsorption capacity, probably due to the formation of highest amount of acidic functional groups during the treatment.
