| Abstract: | Activated carbon has been grafted with amines and the effects of varying the adsorption temperature, the identity of the amine and the pre-treatment conditions on the CO2 adsorption properties of the resulting materials have been investigated. Activated carbon grafted with ethylenediamine at a temperature of 400℃ has the strongest CO2 adsorption capability, with the saturated adsorption capability reaching 12. 35 mg/g. |

| Keywords: | grafted ethylenediamine carbon dioxide adsorption activated carbon surface modification |
