THE SYNTHESIS AND CHARACTERIZATION OF SUCROSE MODIFIED MAGNETITE

Li Jin, Fangtong Liu, Jianpo Zhang

ABSTRACT:Monodisperse air-stable sucrose modified magnetite (SFe3O4) has been prepared by precipitation via a simple and facile hydrothermal reduction route, which was characterized by scanning electron microscopy transmission (SEM), electron microscopy (TEM), energy dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), FT-IR spectroscopy and vibrating sample magnetometry (VSM). SEM and TEM analysis showed the formation of 60 – 80 nm particles. Hysteresis loops indicated that as prepared product could be separated from the nonmagnetic materials in a magnetic field. FT-IR spectra indicated that the carboxylate in this work might bind to the magnetite surface through two oxygen atom, and the sucrose modified magnetite (SFe3O4) was rather stable.
