摘　　要：目的解决烟杆废弃物的燃烧处理造成的资源浪费和环境污染问题,研究实现烟杆废弃物资源化利用。方法通过对烟杆在不同温度下进行热解制备烟杆生物碳,表征烟杆生物碳的形貌、结构和吸附性能,并将其应用于重金属离子吸附。结果研究表明,800℃热解条件下制得的烟杆生物碳具有良好的孔隙结构以及优异的金属离子吸附效果,该生物碳对Cu(Ⅱ)吸附效果最佳,Cd(Ⅱ)次之,Cr(Ⅲ)的吸附效果不显著。结论烟杆制备的生物碳对特定重金属离子具有优异的选择吸附效果,该研究对重金属吸附和污水处理领域的发展有重要的指导意义。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.
