Magnetically separable graphene oxide-based spinel ferrite nanocomposite for water remediation

Abstract In the present time, water pollution has become a serious global concern affecting our eco-system. Compared to traditional methodology, nanotechnology has emerged as a promising technique where it has contributed novel nanomaterials for the treatment of wastewater. The graphene oxide-based spinel ferrite (GOSF) nanocomposite is a novel functional material which has high pollutant removal capacity along with unique characteristics like excellent large specific surface area, easy functionalization, magnetic characteristics, tunable shape and size, high chemical stability, rapid adsorption kinetics, surface active sites, excellent photocatalytic behavior, proper structural order, low electronic bandgap, and less energy requirements and time in the treatment. In addition, due to its magnetic properties, it can easily be recovered after removal of contaminants by the application of an external magnetic field and then reused. The outstanding properties of GOSF nanocomposite may provide revolutionizing tools for water remediation.
