摘要：

Activated carbon was impregnated with 34.57% SnCl2. 2H(2)O salt and then dried at 180 degrees C to produce AC-SnO2 to improve its adsorptive interaction with CO. Besides the fact that activated carbon has its original different pore sizes for normal gas phase CO adsorption (as in the case of pure carbon), the impregnated carbon has additional CO adsorption ability due to the presence of O-(ads) on the active sites. AC-SnO2 proved to be a superior adsorber of CO than pure carbon when used for H-2 purification in a PSA system. Discernibly, the high adsorptive selectivity of AC-SnO2 towards gas phase CO portrays a good future for the applicability of this noble adsorbent, since CO has become: a notorious threat to the global ecosystem due to the current level of air pollution.
