摘要
采用一步法得到含Ni磁性介孔碳(Ni O/C).通过X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)、氮气吸脱附(BET)、拉曼分析、饱和磁化强度等测试对材料进行表征.研究发现,所制备的磁性Ni O/C材料具有介孔结构,可以很好地分散在水溶液中,且有高的磁性能,能通过外加磁场简单快速地进行磁性分离.该材料可以快速、高效吸附水溶液中的离子液体1-甲基-3-丁基咪唑氯盐([Bmim]Cl).
Ni magnetic mesoporous carbon materials was synthesized by one step method. This material was characterized by XRD,SEM,TEM,Nitrogen adsorption-desorption,magnetic measurements and Raman spectra. The results show that the magnetic Ni O / C composite material can be well dispersed in aqueous solution,and exhibit excellent superparamagnetic behaviors. After adsorption,it could be readily separated from solution by applying an external magnetic field. This material can quickly and effective adsorb[Bmim]Cl ionic liquid form aqueous solution.
