- 摘要:
- 采用水热法合成了Fe3O4@MOF-199@C18磁性纳米材料，并以此为吸附剂进行对亚甲基蓝的吸附实验，考察了Fe3O4@MOF-199@C18材料的吸附性能。通过红外光谱、扫描电镜、透射电镜等手段对该磁性材料进行了表征，结果表明此合成材料为质地均匀、表面多孔的磁性纳米材料。Fe3O4@MOF-199@C18磁性纳米材料吸附亚甲基蓝的最佳吸附条件为：pH为4，振荡时间为35 min，材料用量为5 mg，亚甲基蓝初始浓度为3 mg/L时，Fe3O4@MOF-199@C18磁性纳米材料对亚甲基蓝的吸附量为12.81 mg/g。重复利用实验结果表明，Fe3O4@MOF-199@C18材料至少可以重复利用7次。
- Abstract:
- Fe3O4@MOF-199@C18 magnetic nanomaterials were synthesized by hydrothermal method, and the adsorption experiments of methylene blue were carried out with this adsorbent. The adsorption properties of Fe3O4@MOF-199@C18 materials were investigated, and the magnetic material was characterized by FT-IR, SEM, TEM and other means. The results showed that the composite material was a magnetic nanomaterial with uniform texture and porous surface. Fe3O4@MOF-199@C18 magnetic nanoporous materials of methylene blue optimum adsorption conditions were: pH value was 4, shock time was 35 min, the amount of material was 5 mg, methylene blue initial concentration was 3 mg/L, Fe3O4@MOF-199@C18 magnetic nanoporous materials adsorption capacity of methylene blue was 12.81 mg/g. In addition, the resulting Fe3O4@MOF-199@C18 could be reused at least seven times.
