| 摘 要： | 本文以氧化石墨烯为前驱体，采用溶剂热法制备了磁性石墨烯泡沫 (MGF) 复合物。用X-射线衍射(XRD)、透射电镜 (TEM) 及场发射扫描电子显微镜 (FESEM) 等对其进行了表征。在不同的实验参数 (铜离子初始质量浓度、反应时间和温度)下，研究了复合物对水溶液中铜离子的吸附性能。结果表明：Fe3O4成功复合到了石墨烯上且为三维泡沫结构；复合物对铜离子吸附量可达49.20 mg⁄g；吸附过程符合准二级动力学模型。磁性复合物可以借助外部磁场实现快速磁分离。

| Abstract: | Abstract: In this paper, magnetic graphene foam composite was prepared via a solvent thermal method by using graphene oxide as precursor. The composites were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM) and field emission scanning electron microscope (FESEM) respectively. The adsorption behavior of composites for copper ion in aqueous solution was studied at different experimental parameters (initial concentration, reaction time and temperature). The results showed that the Fe3O4 was successfully combined into the grapheme to form the a three-dimensional foam structure. The adsorption amount of copper ion was 49.20 mg⁄g. The adsorption process was in accordance with the quasi two stage kinetic model. Magnetic composite can achieve rapid magnetic separation. |
