主　　题：Fe_(3)O_(4)@C@TiO_(2) Adsorption Oxytetracycline hydrochloride Recycle 

摘      要：The magnetic Fe_(3)O_(4)@C@TiO_(2)microspheres with multilevel yolk-shell structure were successfully prepared by combining sol-gel and simple hydrothermal *** features of the as-obtained Fe_(3)O_(4)@C@TiO_(2)microspheres were investigated by Fourier transform infrared(FTIR)spectra,scanning electron microscopy(SEM),powder X-ray diffraction(XRD),N_(2)adsorptiondesorption measurements and transmission electron microscopy(TEM).Fe_(3)O_(4)@C@TiO_(2)was used as an adsorbent to explore its adsorption properties of oxytetracycline hydrochloride(OTC-HCl)by changing initial concentration and *** results suggest that the maximum adsorption of Fe_(3)O_(4)@C@TiO_(2)is 87.3 mg·g^(-1),and the time reaching the absorption equilibrium is 60 *** model fits to data better than the Freundlich model,and the kinetic properties are well described by the pseudo-second-order *** addition,the synthesized composites’reusability without obvious deterioration in performance is demonstrated by three cycles.
