| 摘 要： | 运用水热合成法制备了一种新型三金属单配体多孔材料Zn/Ni/Cu-BTC，运用氮气吸脱附、扫描电镜、X射线衍射等对材料进行了表征.研究了其常温常压条件下（25℃，1atm）静态吸附刚果红的性能.结果表明，由于三金属不饱和配位点的协同效应导致刚果红在Zn/Ni/Cu-BTC多孔材料上的吸附容量从630mg/g增加到1250mg/g，增加了98.4%.准二级动力学模型和Langmuir吸附模型较好地描述了Zn/Ni/Cu-BTC对刚果红的吸附行为.

| Abstract: | Zn/Ni/Cu-BTC, a new porous material with three metals and one single-ligand, was synthesized by a hydrothermal synthesis method. The material was characterized by N2 adsorption-desorption, SEM and XRD methods. Its adsorptive performance for anion Congo red was investigated at the normal pressure and temperature (25℃, 1ATM) with batch experiments. The result showed that the Congo red uptake capacity increased more than 98% from 630mg/g to 1250mg/g. The adsorption process of Congo red onto Zn/Ni/Cu-BTC could be effectively described by the pseudo-second-order kinetic model and Langmuir adsorption model. |
