Abstract	Adsorption experiment of carbon dioxide was performed on MCM41 silica impregnated with 10~50 wt% EDA (ethylenediamine) and MEA (monoethanolamine) using GC-TCD with U type packed column at 313K isothermal temperature. The prepared adsorbents were characterized by BET surface area, X-ray diffraction and FT-IR. The results showed the best adsorption capacity was shown with MCM-41 impregnated by 30 wt% EDA and more amine impregnation would bring impregnations on surfaces of absorbent. Also, NH$_{2}$ transformed to NH$_{3}$ since silanol groups on surfaces of absorbent and amine were interacted, so that CO$_{2}$ absorption capacities were reduced. Further researches on CO$_{2}$ desorption after adsorption should be followed. Also impregnation efficiency as well as relationships between carbon dioxide concentration and temperature during actual combustion should be investigated.
