In an effort to maximize VOC adsorption, particularly in the case of compounds which are not readily adsorbed on activated carbon cloth (ACC), e.g., acetaldeyde, and to minimize the adsorption of water vapor, several chemical treatments were performed on virgin ACC-20. A sulfuric/nitric acid treatment produced a highly oxidized surface; chemical treatment with NH{sub 3} produced a basic surface and increased the nitrogen content of the ACC; and finally, Cl{sub 2} was used to produce a polar surface. Adsorption isotherms were measured for acetaldehyde, benzene, and water vapor to observe the effect on adsorption capacity for chemically treated ACC-20.
