| 摘 要： | 采用水热法制备了Fe3O4磁性纳米微球,进而用腐殖酸(HA)修饰,成功制备了功能性磁性纳米复合材料(Fe3O4-HA)。并通过紫外可见分光光度计对含有有机染料亚甲基蓝(MB)废水中Fe3O4-HA磁性纳米复合材料的吸附行为进行研究。Fe3O4-HA磁性纳米复合材料的结构和性能用透射电子显微镜、光学接触角测量仪、傅立叶变换红外光谱、X射线衍射仪、振动样品磁强计等手段进行表征。结果表明:Fe3O4-HA磁性纳米复合材料结构均匀,平均粒径约为300 nm,饱和磁化强度为75.3 emu/g。Fe3O4-HA磁性纳米复合材料具有良好的超顺磁性,较高的吸附效率和可重复使用性。

| Abstract: | Functional magnetic nanocomposite ( Fe3O4-HA) was successfully prepared by hydrothermal method，and then
coated by humic acid ( HA) ． Adsorption behavior of the Fe3O4-HA to wastewater containing organic dye methylene blue
( MB) was studied by ultraviolet and visible spectrophotometer． The structure and property of the Fe3O4-HA were
characterized by transmission electron microscopy，optical contact angle，fourier transform infrared spectroscopy，X ray
diffractometer，vibrating sample magnetometer． The results demonstrate that Fe3O4-HA has a homogeneous structure，and its
average particles size is about 300 nm and the saturation magnetization is 75. 3 emu /g． This synthetic Fe3O4-HA
nanocomposite has good superparamagnetism，high adsorption efficiency and reusability． |
