Water vapor adsorption on activated carbon cloth (ACCBO) which has been oxidized to a level of 32% oxygen exhibits a unique isotherm with uniform hysteresis of small magnitude upon desorption. In contrast the adsorption on untreated ACCBO and chemically modified ACCBO (7.8% Cl), ACCBO (16% Cl), and ACCBO (4% N), exhibits sigmoidal isotherms with hysteresis loops of varying magnitudes. The latte...
