摘要:
为了得到具有良好吸附性能的石墨烯与含铁氧化物的复合材料,在碱性条件下通过亚铁离子与氧化石墨烯的一步反应制备石墨烯与四氧化三铁复合材料. 采用X射线衍射、扫描电子显微镜和热失重分析对该复合材料的结构与微观形貌进行表征,并研究了石墨烯与四氧化三铁复合材料对罗丹明B的吸附性能. 实验结果表明,亚铁离子在碱性条件下生成的四氧化三铁纳米颗粒较均匀地分布在石墨烯表面,破坏了石墨烯原有的结晶结构. 与单独的石墨烯或者四氧化三铁相比,复合材料对罗丹明B有良好的吸附性能. 吸附染料的复合材料可以用磁铁从溶液中移出,有利于复合材料的回收与重复使用. 研究其吸附动力学和吸附等温线发现,该复合材料吸附罗丹明B符合准二级动力学方程和Langmuir吸附模型.
Abstract:
The composites of graphene and ferriferrous oxide were fabricated by a one-pot process via the reaction of ferrous ions and alkaline condition.The structure and the property ofgraphene and ferriferrous oxide composites were characterized byX-ray diffraction ,scanning election microscope and thermogravimetric analisis.The experimental results show that ferrous ions are covered to ferriferrous oxide in alkaline condition;ferriferrous oxide nanoparticles are distributed uniformly on the graphene surface,which changes the crystalline structure of graphene oxide ;the graphene and ferriferrous oxide composites can be used as an efficient adsorbent for the removedof rhodamine B in aquceous solution;moreover,it is easy to be removede from the waste solution by external magnet.the adsorption isotherms andkinetics are well described by the Langmuir and pseudo secong-order model respectively.
