  • 摘要: 以二甘醇/乙二醇醇热法制备了超顺磁性纳米Fe3O4，采用场发射扫描电子显微镜（FE-SEM）、X射线衍射（XRD）以及磁滞回线等手段对制备的纳米Fe3O4进行表征，并通过纳米Fe3O4/ H2O2类Fenton反应降解罗丹明B废水考察了纳米Fe3O4/H2O2的性能及其稳定性。研究表明，制备的纳米Fe3O4不仅分散性好、规整球状结构，磁性强且粒径比较均匀，平均粒径约为80 nm；从单因素实验（纳米Fe3O4投加量、H2O2/Fe3O4的摩尔比、pH以及反应时间）与正交实验获得了最佳反应条件：纳米Fe3O4投加量为2 g·L-1，pH=4，H2O2/Fe3O4摩尔比为4：1，反应时间为3 h，此时罗丹明B与TOC去除率分别为100%和35%。重复4次使用纳米Fe3O4，通过表征发现纳米Fe3O4颗粒的晶体结构不变但是发生了团聚，纳米Fe3O4的催化性能有所下降。
    Abstract: Using diethylene glycol/ethylene glycol alcohol as a solvent, superparamagnetic Fe3O4 was prepared using a hydrothermal method and was characterized by field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and magnetic performance testing.From the Fenton-like reaction of nano-Fe3O4/H2O2 to degrade rhodamine B, the catalytic performance and stability of nano-Fe3O4 on H2O2 were investigated.The results revealed that prepared nano-Fe3O4 possessed well-defined globular structure with uniform particle size of approximately 80 nm and showed high dispersion and strong magnetism as well.Combining the results of single factor experiments (nano-Fe3O4 dosage, H2O2/nano-Fe3O4 molar ratio, pH, and reaction time) and orthogonal experiments, the optimum reactive conditions were determined as:dosage of nano-Fe3O4 is 2 g·L-1, pH is 4, molar ratio of H2O2 to nano-Fe3O4 is 4:1, and reaction time is 3 h.With this understanding, the removal rates of rhodamine B and TOC were 100% and 35%, respectively.The catalytic performance of nano-Fe3O4 was weakened after it was reused four times because of aggregation.
