摘要

The excessive use of antibiotics has led to various environmental problems; the control and separation of these antibiotics are important in environmental science. Herein, a novel mesoporous nanocomposite, Fe3O4@SiO2@mSiO(2)-CD, has been synthesized for the removal of antibiotic compounds from aqueous media. The well-designed nanocomposite is composed of -cyclodextrin functionalized surfaces, ordered mesoporous silica shells with large radially oriented mesopores, and nonporous silica-coated magnetic cores (Fe3O4). The synergistic action of both the mesoporous structure and the accessible cavity of -cyclodextrin ensures the good adsorption of doxycycline. Furthermore, the Fe3O4@SiO2@mSiO(2)-CD nanocomposite can be collected, separated and easily recycled from aqueous solution using an external magnet.
