The techniques used to study the oxygen adsorption properties were a static adsorption technique to measure the amount of adsorbed oxygen and a dynamic adsorption technique to measure the heat of adsorption.

The amount of O2 adsorption increased in the first 1 h of oxidation time and then reached saturation. The heat of adsorption showed an abrupt decrease for the 0.5 h oxidation treatment, followed

All these data are summarized in Table 2 and systematically compared with those reported in the literature for related CTF systems.

The isosteric heat of adsorption values are calculated to quantify the nature of the interaction between the SO2 molecule and the adsorbent. Most importantly, while chemisorption is
