A radiotracer technique was employed to study the sorption of As(III) and As(V) on chemically synthesized iron oxides: magnetite (Fe3O4), goethite (α-FeOOH) and hematite (Fe2O3) by batch equilibration mode. Magnetite and goethite were found to be promising sorbents for arsenic removal and applied to real ground water from West Bengal, India. A solvent extraction method using benzene was applied for the investigation of oxidation state of sorbed arsenic. A sorption mechanism was proposed for interaction of As(III)/As(V) with iron oxides.
