The adsorption/desorption isotherms of water vapor are measured on two commercial activated carbons (ACs) at three temperatures (353, 369, and 386 K) by means of a magnetic suspension balance. These two ACs are fully characterized in terms of textural properties (specific surface area and pore size distribution) and surface active groups concentrations by Boehm titration. The effect of temperature and textural properties of the ACs is analyzed both on the adsorption/desorption hysteresis and on the total adsorptive capacity. The Do and Do model and two modified versions of this latter are compared for the modeling of all the experimental isotherms.
