The aim of this study is to carry out a comparative assessment of the potentials of amine functionalized cow bone residue (CB) and coconut shell (CS) activated carbon for carbon (iv) oxide (CO2) adsorption. The two samples were subjected to carbonization and subsequent functionalization with triethanolamine. The functionalized activated carbons were characterized for its functional groups and surface area using Fourier Transform Infrared Spectrometer (FTIR) machine. The effect of time (5, 10, 15, 20 and 25 min) and temperature (40, 50 and 60°C) on the rate of CO2 adsorption were investigated. The optimum quantity of CO2 adsorbed were 65 and 52 mg/g for CS and CB at a temperature of 60°C and adsorption time of 20 min respectively. The result of FTIR analysis revealed a stretching vibrations at 1331 cm-1 indicating the CO2 adsorbed. The study has demonstrated that the CB and CS activated carbon can be effectively used as an adsorbent for CO2 sequestration and storage.
