摘要
使用水热合成法制备了MIL-100样品,考察了初始质量浓度、温度、时间对MIL-100吸附亚甲基蓝性能的影响。结果表明,在100mg/L的亚甲基蓝溶液中,30min内溶液脱色率即可达到80%以上;在360min左右即可达到吸附平衡,且亚甲基蓝溶液的脱色率达97%以上。实验结果能够较好地符合Langmuir吸附等温式以及二级动力学模型。
MIL-100 was prepared by hydrothermal synthesis.The use of MIL-100 for the removal of methylene blue from aqueous solution at different initial concentration,temperature and time was investigated.Results indicate that： 80% of methylene blue was adsorbed within 30 min at an initial concentration of 100 mg/L;the adsorptions reached equilibrium in about 360 min and the decolorization rate of methylene blue was more than 97%.The adsorption kinetics and isotherm of methylene blue on MIL-100 were investigated in detail,and the kinetic and equilibrium adsorptions were well-modeled using pseudo second-order kinetics and Langmuir isotherm model,respectively.
