摘要：

Highly toxic gases such as hydrogen sulfide (H2S), carbon dioxide (CO2), and ammonia (NH3) are generated by both nature and human activities and affect human health. In this research, activated carbon combined with Ca(OH)(2) and CaCO3 (AC-CO and AC-CC, respectively) were fabricated and applied in absorbing toxic gases from air pollutants. Activated charcoal powder was compressed in the form of pellets and used in the designated conditions. The optimum operating conditions and material properties, such as adsorption capacity, effect of weight ratio of the mixture, and hardness, have been investigated after combining with the calcium derivative. The good performance exhibited in this study suggests that this material is expected to be an effective and economically viable adsorbent for NH3, CO2, and H2S removal from the air system.
