实验通过制备Fe_3O_4@MOF-199复合材料,并以其作为吸附剂,对甲基蓝进行吸附研究。并对材料进行扫描电镜(SEM)的表征。通过研究pH值,吸附剂用量,震荡时间等单因素和饱和吸附量来探究Fe_3O_4@MOF-199纳米复合材料的吸附性能。实验结果表明,Fe_3O_4@MOF-199纳米复合材料吸附对甲基蓝吸附的最佳条件为pH值为6,吸附剂添加量为5 mg,震荡时间为60 min。该实验结果表明Fe_3O_4@MOF-199纳米复合材料是去除水中甲基蓝的优良吸附剂。
In the experiment, Fe 3 O 4 @ MOF-199 composite was prepared and used as adsorbent to study the adsorption of methyl blue. The materials were characterized by scanning electron microscopy (SEM). The adsorption properties of Fe_3O_4 @ MOF-199 nanocomposites were investigated by studying single factor and saturated adsorption capacity such as pH value, adsorbent dosage and shaking time. The experimental results show that the optimum conditions for adsorption of methyl blue on Fe_3O_4 @ MOF-199 nanocomposites are pH value of 6, adsorbent dosage of 5 mg and shaking time of 60 min. The experimental results show that Fe_3O_4 @ MOF-199 nanocomposites are excellent adsorbents for the removal of methyl blue in water.
