Preparation and Characterization of Amino Functionalized NiFe2O4@SiO2 Magnetic Nanoparticles

In this research, nickel ferrite magnetic nanoparticles were prepared from iron and nickel salts, then NiFe2O4(MNPs) were coated with silica shell of tetraethoxysilane (TEOS). Finally NiFe2O4/SiO2, core/shell functionalized by amino propyltriethoxysilane(APTES). This structures were characterized, by atomic absorption (AA), FT-IR spectroscopy, power X-ray diffraction(XRD), scanning electron microscope(SEM). This product can be used as a support of transition metals complexes To absorb environmental pollutants (especially heavy metals).
