| Abstract: | In order to improve the carbon dioxide adsorption capacity on china-made activated carbon, its oxidative treatment with hydrogen peroxide, nitric acid and cupic acetate was carried out . The results showed that the modified surface had important effects on the carbon dioxide adsorption capacity and surface acid groups. The measured characteristic free energy of adsorption was affected by acid groups of activated carbon. |
