掺杂Ba 2+ 改善锌铁氧体/还原氧化石墨烯的吸附性能和磁性能(英文)
发布时间:2021-04-25 19:21
以Ba2+、Fe3+、Zn2+和氧化石墨烯(GO)为原料,采用一步溶剂热法制备了Ba2+掺杂的锌铁氧体/还原氧化石墨烯(Ba2+-ZF/rGO)磁性吸附剂材料。在反应过程中,实现了Ba2+掺杂锌铁氧体(Ba2+-ZF)的合成、GO的还原以及两相的复合等过程的同步进行,一步合成了Ba2+-ZF/rGO复合材料。实验结果表明,无机粒子均匀地分散在还原氧化石墨烯(r GO)基底上,且无团聚现象。Ba2+-ZF/rGO复合材料对染料分子具有优异的吸附性能,且吸附过程符合准二级动力学模型。特别地,Ba2+、Fe2+(来源于Fe3+的还原)的引入极大地改善了复合材料的磁性能,显示出了良好的磁分离性。因此,本实验合成的Ba2+-ZF/rGO复合材料是一种高效且具有良好磁分离性的吸附剂材料。
