β-CD@Fe3O4 Nano-Intelligent Magnetic Material

Oily sludge is one of the main pollutants produced in oil extraction and transportation. It has the characteristics of large output, complex composition, and difficult handling. A nano intelligent magnetic material β-CD@ Fe3O4 was prepared by hydrothermal and surface modification methods. Its size is about 300nm, which can intelligently find the oil-water interface and the oil-solid interface.油污泥是石油开采与运输过程中产生的主要污染物之一。其具备产出量大、成分复杂、处理难度大的特点。本研究通过水热法与表面改性法制备了一种纳米智能磁性材料β-CD@Fe3O4，该材料粒径约为300nm，可智能识别油水界面与油固界面。
