一种C/γ-Fe2O3复合材料循环使用的方法
摘要：
本发明提供一种C/γ-Fe2O3复合材料循环使用的方法，包括如下步骤：(1)将C/γ-Fe2O3复合材料洒落在油水或者染料污水表面，鼓泡搅拌充分吸附染料或者油；(2)电磁铁进行通电，将C/γ-Fe2O3进行磁性回收；(3)电磁铁断电，将回收的吸附油或者染料的C/γ-Fe2O3复合材料分散在有机溶剂中，鼓泡搅拌；(4)电磁铁再通电，将已经脱附的C/γ-Fe2O3复合材料磁性吸附后，再次洒在有机溶剂中脱附，重复3-5次后，回收的C/γ-Fe2O3复合材料，烘干后，循环使用。该方法工艺简单，易于操作，利用材料特性实现磁性油水分离，连续性强，很好的解决了传统碳材料不易再生的问题，实现资源回收再利用。
摘要（英）：

The present invention provides a C/gamma-Fe2O3 composite material recycling method, which comprises: (1) sprinkling a C/gamma-Fe2O3 composite material onto the surface of oil water or dye sewage, and carrying out bubbling stirring to completely adsorb the dye or oil; (2) electrifying an electric magnet, and carrying out magnetic recovery on the C/gamma-Fe2O3; (3) carrying out power-down on the electric magnet, dispersing the recovered C/gamma-Fe2O3 composite material of the absorbed oil or dye in an organic solvent, and carrying out bubbling stirring; and (4) electrifying the electric magnet again, carrying out magnetic adsorption on the desorbed C/gamma-Fe2O3 composite material, sprinkling in an organic solvent again, carrying out desorption, repeatedly performing the steps 3-5 times, recovering the C/gamma-Fe2O3 composite material, and drying so as to be recycled. According to the present invention, the method has characteristics of simple process and easy operation; the characteristics of the material are used to achieve the magnetic oil water separation; and the continuity is strong, the problem that the traditional material is not easily regenerated is well solved, and the resource recycling and re-use is achieved.
