제목 A study on adsorption characteristics of ammonia over modified activated carbons
초록 Physical properties of activated carbons (ACs) modified with various acids were investigated by infrared (IR) and N2 gas adsorption at 77K. Adsorption of NH3 over various acids modified ACs was carried out to determine the relationship between the adsorption capacity and physical properties of the modified AC. Among the acid modified ACs, H3PO4 modified AC (PA/AC) showed the best adsorption capacity. The amount of NH3 adsorbed was increased with increasing H3PO4 contents for modification, but was suddenly decreased at H3PO4 content of above 20wt%. Relationship between the physical properties and amount of NH3 adsorbed was not clear, but it was thought that the adsorbed amount could be depended on functional group of surface.
