摘      要：We studied the capacity of activated carbon (C1) to adsorb NO at different temperatures using a glass, high-vacuum volumetric system to obtain information on the energy characteristics of the adsorption process. Adsorption equilibrium data were analysed by the Freundlich isotherm equation using regression analysis. We employed the Clausius–Clapeyron relationship to calculate the isosteric heats of NO adsorption using the equilibrium data of the isotherms measured at 273 and 293 K. The amount of NO adsorbed during reversible adsorption was higher than that adsorbed during total adsorption, probably due to semiquinones formation during total adsorption, which increased both the adsorption capacity of NO and adsorbate–adsorbent interactions during reversible adsorption.
