| 摘 要： | 以乙二醇为溶剂，通过温和的溶剂热法制备了具有不同颗粒尺寸大小的Fe3O4微米粒子.研究发现，通过调节反应体系中水、聚乙二醇-20000和铁离子的浓度，能有效控制Fe3O4的成核与生长，从而能实现对Fe3O4在较大颗粒尺寸范围内的有效调控.另外，相比小尺寸的Fe3O4，较大颗粒尺寸的超顺磁性粒子表现出更优良的磁性回收性能.由此可见，Fe3O4颗粒尺寸的有效调控对拓展其在纳米材料磁性回收中的应用具有非常重要的意义

| Abstract: | Fe3O4 microparticles of different size were synthesized by a novel solvothermal method，using ethylene glycol as solvent. It is found that the nucleation and growth of Fe3O4can be effectively controlled through adjusting the concentrations of water，polyethylene glycol 20000，and iron ion，which creates the possibility of controlling the size ofFe3O4 in a wide range effectively.Besides，Fe3O4 microparticle of larger size exhibits more excellent magnetic recycling property.As discussed above，the effective control ofFe3O4 particle is very important to expand its application in magnetite recovery of nanomaterials. |
