Abstract

The effect of mechanical treatment of γ-Fe2O3 in a planetary ball mill on the physicochemical and sorption properties of the powders obtained was studied. The mechanical treatment in the presence of ethanol allows preparation of single-phase γ-Fe2O3 powders exhibiting high adsorption capacity for Co(II) ions. The sorption characteristics of the mechanically activated γ-Fe2O3 powders depend on the mechanical treatment parameters. The sorbents that take up Co(II) ions from aqueous solutions most efficiently, with the maximal adsorption capacity of up to 0.43 mmol g−1, can be prepared at maximal rotation rates of the mill drum.
