| 英文摘要 | Man-made pollution is hazardous to both the environment and human health. This study attempts to develop a low-cost, biobased adsorbent for CO2 capture and heavy metal removal. The adsorption behavior of CO2 from air and Pb (II) from aqueous systems onto polyethylenimine (PEI) modified biochar was studied. Chemical and physical pretreatments were performed in an attempt to enhance the adsorption kinetics of biochar. FT-IR and Elemental Analysis were performed to confirm the loading of PEI onto the surface of biochar was achieved. The efficiency of the PEI modified biochar on the removal of Pb (II) from aqueous solutions was determined by Atomic Absorption Spectrometer (AAS). Alkali pretreatment of PEI modified biochar increased CO2 capture and removal of Pb(II). This experiment introduces a new approach to air and water purification by using the combination of an amine with biochar. |
