This study investigates the adsorption performance of spinel nanostructures-embedded graphene oxide (GO) for removing toxic Pb2+ ions from water. The graphene oxide nanocomposites containing Fe3O4, CoFe2O4, and NiFe2O4 nanoparticles were synthesized and characterized. The NiFe2O4/GO nanocomposite exhibited the highest Pb2+ adsorption capacity, reaching 96.1% removal at 75 minutes contact time with initial Pb2+ concentration of […]
