Fe基MOF的制备及其吸附性能数据集

采用一步水热法成功制备了NH2-MIL@L，优化了NH2-MIL@L在一元和二元染料体系吸附MO和MB的工艺条件。在一元染料体系中，NH2-MIL@L通过π–π相互作用、氢键、静电和配位作用吸附MO，最大吸附量为195.31 mg/g，NH2-MIL@L对MO的吸附效率仅在5 min可达95.09%。在二元染料体系中，NH2-MIL@L通过π–π相互作用、氢键、静电和配位作用吸附MO和MB，对MO的最大吸附量为438.6 mg/g，对MB的最大吸附量为481.34 mg/g。MB与MO之间存在静电吸引作用使得NH2-MIL@L对MO的吸附仅在15 min达到吸附平衡。与NH2-MIL@L相比，NH2-MIL@L对MO和MB的吸附量增加，吸附平衡时间缩短，吸附过程基本不受pH变化影响。NH2-MIL@L经过5次洗脱实验对染料的吸附效率仍有90%。NH2-MIL@L was successfully synthesized via one-step hydrothermal method, and the adsorption process conditions of MO and MB onto NH2-MIL@L in both monomeric and binary dye systems were optimized. In the monomeric dye system, NH2-MIL@L adsorbs MO through π-π interactions, hydrogen bonding, electrostatic interactions and coordination interactions, with a maximum adsorption capacity of 195.31 mg/g, and its adsorption efficiency towards MO reaches 95.09% within only 5 minutes. In the binary dye system, NH2-MIL@L adsorbs both MO and MB via the aforementioned intermolecular interactions, with maximum adsorption capacities of 438.6 mg/g for MO and 481.34 mg/g for MB, respectively. The electrostatic attraction between MB and MO enables the adsorption equilibrium of MO onto NH2-MIL@L to be achieved within only 15 minutes. Compared with NH2-MIL@L, NH2-MIL@L exhibits increased adsorption capacities towards MO and MB, shortened adsorption equilibrium time, and its adsorption process is barely affected by pH changes. After 5 cycles of elution experiments, NH2-MIL@L still maintains an adsorption efficiency of 90% towards the dyes.
