| 摘 要： | 采用共沉淀法制备腐殖酸包覆的磁性四氧化三铁纳米粒子(HA@Fe_3O_4)并将其用于类Fenton体系催化降解亚甲基蓝(MB).通过透射电子显微镜(TEM)、动态光散射(DLS)、X射线衍射仪(XRD)、傅里叶变换红外光谱(FT-IR)对样品的形貌、结构及成分进行表征.比较HA包覆前后Fe_3O_4纳米粒子的催化效果,考察HA@Fe_3O_4催化剂用量、H_2O_2浓度等因素对降解效率的影响.结果表明HA的包覆可以显著提高MB的降解效率.

| Abstract: | Humic acid coated Fe3O4 magnetic nanoparticles (HA@Fe3O4) were prepared by coprecipitation method. The morphology, structure and composition of the magnetic nanoparticles were characterized by transmission electron microscope (TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), and Fourier-transform infrared (FT-IR) spectra. The effects of catalyst addition and hydrogen peroxide (H2O2) concentration on the degradation efficiency were investigated by choosing the methylene blue (MB) as the degradation model and HA@Fe3O4 as catalysts. The result showed that the coating of HA obviously accelerated the degradation rate of MB. |
