Physical and chemical properties of nitrogen-containing active carbons (ACs), having a much higher activity and capacity for SO<SUB>2</SUB> adsorption than commercial ACs, were investigated to define suitable properties for SO<SUB>2</SUB> removal. The capacity of nitrogen-containing ACs for SO<SUB>2</SUB> adsorption correlates with the amount of their surface basic groups. However, the amount of basic surface groups for the ACs is practically the same as that for commercial ACs, indicating that the ACs have another characteristic property effective for SO<SUB>2</SUB> removal. A study on the chemical state of surface nitrogen atoms by means of an X-ray photoelectron spectrometer has revealed that surface nitrogen species are effective for SO<SUB>2</SUB> adsorption.
