磁性花生壳生物碳的制备及其吸附性能综合实验设计

The biochar was prepared by pyrolysis method, using different biomass as raw materials. By screening, peanut shell biochar was selected, and Fe3O4 magnetic material was loaded for treatment of tetracycline in water sample. The magnetic peanut shell biochar was characterized by scanning electron microscop (SEM), specific surface area analyzer (BET) and X-ray diffraction (XRD), and the adsorption kinetics, isotherm characteristics and various factors affecting the removal effect were studied. Through this comprehensive experiment, students can establish the idea of "treating waste with waste", and master the method of preparing adsorbent using waste, material characterization technology and pollutant regulation methods. In addition, this experiment can improve students' awareness of innovation and the ability to apply what they have learned to solve practical problems.
