Miêu tả
Tóm tắt: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. The composite that resulted with the best properties in terms of contact surface area and saturation of magnetization was selected for Pb<sup>2+</sup> adsorption studies from aqueous media. The material presented good absorption capacity (maximum adsorption capacity 14.9 mg·g<sup>−1</sup>) comparable with similar materials presented in literature. Its chemico-physical stability and adsorption capacity recommend the nanocomposite as a cheap adsorbent material for lead.
