Abstract

The surface of synthetic magnetite (Fe3O4) and maghemite (γ-Fe2O3) nanoparticles was modified with phosphonic chelating compounds, 1-hydroxyethane-1,1-di(phosphonic acid) and nitrilotris(methylenephosphonic acid). The sorption affinity of functionalized magnetic iron oxides towards Niii under acidic conditions was increased by one order of magnitude.
