【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。更多还原

【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.更多还原
