磁性Fe3O4@MIL-100(Ni)的制备及其对罗丹明B的吸附
Preparation of Magnetic Fe3O4@MIL-100(Ni)and Adsorption of Rhodamine B
【摘要】 金属-有机骨架材料(MOFs)是通过共价键构成的三维多孔材料,具有较大比表面积和可调的孔径。采用层层组装的方法,成功制备了球形的磁性核-壳多孔吸附剂Fe3O4@MIL-100(Ni),比表面积达到了193.42m2/g,对水溶液中罗丹明B染料具有较强的吸附能力。pH值小于3时,吸附达到最佳。同时,Fe3O4@MIL-100(Ni)的磁性使得其极易磁性回收再处理。
【Abstract】 Metal-organic framework materials(MOFs)are three-dimensional porous materials composed of covalent bonds,which have a large specific surface area and adjustable pore sizes.In this paper,a spherical magnetic core-shell porous adsorbent Fe3 O4 @ MIL-100(Ni)was successfully prepared using a layer-by-layer assembly method,with a specific surface area of 193.42 m2/g,which has strong adsorption for rhodamine B dye in aqueous solution.ability.When pH is less than 3,adsorption is optimal.At the same time,the magnetic properties of Fe3 O4@MIL-100(Ni)make it extremely easy to recover and process magnetically.
