| The work aims to research the resource utilization of tobacco stalk waste to solve the great waste of resources and environmental pollution caused by combustion treatment of tobacco stems.The morphology, structure and adsorption properties of the tobacco stem biochar were characterized by pyrolysis of tobacco stems at different temperature, and the ions adsorption of heavy metals were applied. The results showed that the tobacco stem biochar produced during pyrolysis at 800 °C had a good pore structure and excellent metal ion adsorption effect, and its adsorption effect on Cu(Ⅱ) was the best, followed by Cd(Ⅱ). That on Cr(Ⅲ) was not significant. The biochar prepared from tobacco stems has excellent selective adsorption effect on specific ions, and this study has important guiding significance for the development of heavy metal adsorption field. |
