Abstract

The adsorption of boron on Fe₃O₄ nanoparticles was studied by metal doping. The changes in the oxygen binding energy of doped Fe₃O₄ were found to negatively correlate with boron adsorption capacity, where Mg and Zn doped Fe₃O₄ exhibited an obvious increase by 60% and 15%, respectively. The adsorption of boron might proceed through nucleophilic attack of the hydroxyl group on magnetite toward the vacant orbital of the boron center.
