Silica-Coated Magnetic Nanocomposites for Pb<sup>2+</sup> Removal from Aqueous Solution
Magnetic iron oxide-silica shell nanocomposites with different iron oxide/silica ratio were synthesized and structurally characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), small-angle neutron scattering, magnetic and N<sub>2</sub>-sorption studies....
