Preparation and Adsorptive Performance of Transition Metal Oxide Nanoparticles in Removal of Fe(III) Ions

Abstract

In this study, we focus on preparation and adsorptive performance of transition metal oxide nanoparticles in removal of Fe(III) ions. The prepared nanoparticles including iron oxide (Fe₂O₃), cobalt oxide (Co₃O₄) and manganese oxide (Mn₂O₃/Mn₃O₄) nanocomposite provide a good affinity for Fe(III) ions adsorption from aqueous systems. Among them, Fe(III) ions were adsorbed by manganese oxide (Mn₂O₃/Mn₃O₄) nanocomposite with a higher removal ratio compared to the other nanoparticles.
