摘要

首先通过溶剂热法制备Fe₃O₄纳米颗粒,再通过离子强度调控法制备磁性氧化石墨烯(Fe₃O₄/GO),最后用共沉淀法制得Fe₃O₄/GO/CeO₂复合纳米材料,并用扫描电镜(SEM)、能量色散X射线光谱(EDX)、X射线衍射(XRD)等技术对其进行表征。结果表明:Fe₃O₄纳米颗粒与CeO₂纳米颗粒均匀地分散在GO上。研究了Fe₃O₄/GO/CeO₂复合纳米材料对亚甲基蓝染料的吸附性能,并考察了不同因素对吸附性能的影响。由于Fe₃O₄纳米颗粒有着磁性的性质,易回收分离,具有再生利用性能。吸附实验结果表明:Fe₃O₄/GO/CeO₂复合纳米材料循环5次后对亚甲基蓝的吸附率仍在95%以上。因此,Fe₃O₄/GO/CeO₂复合纳米材料是一种新型优良的吸附剂材料,被应用于模拟染料废水中的亚甲基蓝去除研究。

Abstract

Firstly,Fe₃O₄ nanoparticles were prepared by solvothermal method,and then magnetic graphene oxide (Fe₃O₄/GO) was obtained by ionic strength control method.Finally,Fe₃O₄/GO/CeO₂ composite nanomaterials were prepared by co-precipitation method,and were further characterized by SEM,EDX,XRD and so on.The results showed that Fe₃O₄ nanoparticles and CeO₂ nanoparticles were uniformly dispersed on GO.The adsorption properties of Fe₃O₄/GO/CeO₂ composite nanomaterials for methylene blue dyes were studied,and the effects of different factors on the adsorption properties were also investigated.Due to the magnetic properties of Fe₃O₄ nanoparticles,it was easy to be recovered and separated,which made the composite materials have recycling properties.The results revealed that the adsorption rate of Fe₃O₄/GO/CeO₂ composite nanomaterials for methylene blue retained above 95% after 5 cycles.Therefore,Fe₃O₄/GO/CeO₂ composite nanomaterial,as a new excellent adsorbent material,could be applied in the area of methylene blue removal from simulated dye wastewater.
