摘要
本文以来源丰富的浮萍为原料,通过水热-炭化法制备出磁性碳微球。研究采用扫描电镜(SEM)、X射线衍射(XRD)和比表面积等技术对碳微球进行表征。结果表明,碳微球大小均匀,含有丰富的N和P,比表面积达179.8m^(2)/g,磁化强度为0.83emu/g。通过测试其对水中抗生素的吸附特性,发现该材料吸附平衡快,吸附等温线符合Freundlich模型,有望为环境修复工作提供一种可持续且高效的吸附材料。
This paper utilises the abundant resource of duckweed as raw material to prepare magnetic carbon microspheres through a hydrothermal-carbonisation process.The study employs techniques such as scanning electron microscopy(SEM),X-ray diffraction(XRD),and specific surface area analysis to characterise the carbon microspheres.The results indicate that the microspheres exhibit uniform size,are rich in nitrogen and phosphorus content,possess a specific surface area of 179.8 m^(2)/g,and have a magnetisation strength of 0.83 emu/g.Through testing their adsorption characteristics for antibiotics in water,it was found that the material achieves rapid adsorption equilibrium,with the adsorption isotherms conforming to the Freundlich model.This suggests the potential of these microspheres as a sustainable and efficient adsorbent for environmental remediation efforts.
