Abstract:

The regular-shaped (triangular pyramid) metal organic framework (MOF) material MIL-53(Fe) has been prepared by a hydro-thermal method, and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).Using congo red as model pollutant, the adsorption effect of the prepared MIL-53(Fe) MOF material on congo red is investigated.The results show that the adsorption kinetics of MIL-53(Fe) for congo red complies with pseudo-second-order kine-tics and the adsorption model complies with Langmuir isotherm model.The maximum adsorption capacity of MIL-53(Fe) material for congo red is 1 482 mg/g.It is expected that MIL-53(Fe) MOF can be used as highly efficient adsorption material for removing congo red from dyestuff wastewater.

Key words: metal organic framework material, MIL-53(Fe), adsorption, congo red

摘要:

通过水热法制备规则外形的MIL-53(Fe)金属有机骨架材料(MOF),并通过傅里叶红外光谱(FT-IR)、X射线衍射(XRD)、扫描电镜(SEM)和透射电镜(TEM)对材料进行表征。以刚果红作为目标物,研究所制得的MOF材料对其的吸附行为。结果表明,MIL-53(Fe)对刚果红的吸附动力学符合准二级动力学,吸附模型符合Langmuir吸附模型。MIL-53(Fe)材料对刚果红的最大吸附量为1 482 mg/g,是可望用于去除染料废水刚果红的高效吸附材料。
