In this work, the adsorption behaviors of activated carbons (ACs) containing chelating functional groups were studied in carbon dioxide removal. The ACs were modified by pyrolysis of peroxide and glycidyl methacrylate graft polymerization in order to induce chelating functional groups, such as diethylenetriamine groups on the AC surfaces. The surface functional groups of the ACs were characterized by Fourier transform-infrared spectrometry (FT-IR) and X-ray photoelectron spectroscopy (XPS). The textural properties of the ACs were analyzed by N2/77 K isotherms. Adsorption behaviors of the ACs were observed in the amounts of CO2 adsorption. From the results, we found that CO2 adsorption behaviors were strongly influenced by introducing of the chelating functional groups on AC surfaces. |
