Adsorption experiment of carbon dioxide was performed on MCM41 silica impregnated with two kinds of EDA(ethylenediamine) and MEA(monoethanolamine). The prepared adsorbents were characterized by BET surface area, X-ray diffraction and FT-IR. The $CO_2$ capture study was investigated in a U type packed column with GC/TCD. The results of XRD for MCM-41 and amine-impregnated MCM41 showed typical the hexagonal pore system. BET results showed the MCM 41 impregnated amine to have a surface area of 141 $m^2/g$ to 595 $m^2/g$ and FT-IR revealed a N-H functional group at about 1400$cm^{-1}$ to 1600$cm^{-1}$. The $CO_2$ adsorption capacity on EDA and MEA was as follow: MCM41-EDA30 > MCM41 -EDA40 >MCM41-EDA20 >MCM-EDA10 and MCM41-MEA40 >MCM41-MEA30 > MCM41-MEA20> MCM41-MEA10. The MCM41-EDA30 showed the highest adsorption capacity due to physical adsorption and chemical adsorption by amino-group content. The results suggest that mesoporous media with EDA is effective adsorbent for $CO_2$ capture from flue gases.
