| 中文摘要 | 采用化学共沉淀法制备了磁性纳米Fe3O4颗粒,应用透射电子显微镜(TEM)、X射线衍射仪(XRD)和振动样品磁强计(VSM)对纳米Fe3O4颗粒的粒径、结构、形貌和磁学性能进行了表征和分析,并对其在染料废水处理中的应用进行了研究。结果表明,化学共沉淀法制备得到的纳米Fe3O4颗粒主要呈球状,平均粒径约为11.7nm,饱和磁化强度、矫顽力和剩余磁化强度分别为67.7emu/g,5.32Gs,1.6emu/g,具有超顺磁性。纳米Fe3O4颗粒能够快速处理含有罗丹明B的染料废水,并与活性炭粉末的处理效果进行了对比。纳米Fe3O4颗粒可从废水中快速分离,并具有良好的重复利用性能。; Fe3O4 magnetic nanoparticles were synthesized by chemical coprecipitation method.The particle size,structure,morphology and magnetic property of the nanoparticles were characterized and analyzed.The application of the nanoparticles in treatment of dye wastewater was studied.The results showed that the nanoparticles were spherical,the size of prepared sample was about 11 nm.The saturation magnetization,coercivity,residual magnetization were 67.7emu/g,5.32 Gs and 1.6emu/g,respectively.The nanoparticles possessed superparamagnetism.The nanoparticles exhibited high removal efficiency of RhB contained in dye wastewater and compared with activated carbon.The nanoparticles can also rapidly separated from wastewater using a magnet and exhibited better performance of repeated use. |
