Functionalized nano magnetic Fe3O4/SiO2 core-shell as efficient adsorbent for removal of Pb2+ from aqueous solutions

摘要: Development of reliable adsorbents with high adsorption capacity, fast adsorption-desorption kinetics is of significant importance. Nanosized magnetic particles having high surface area and unique advantage of easy separation by external magnetic field are considered as potential adsorbents for removal of heavy metal cations from aqueous solutions. In this research, synthesis of Fe 3 O 4-SiO 2 core-shell and its efficiency for removal of Pb 2+ from aqueous solution has been reported. In order to increase the …
