Abstract
Sorption properties of commercial hematite (α-Fe2O3) for divalent copper ions were studied. This was done with a model solution of copper(II) sulfate additionally containing 400 mg L–1 of sodium sulfate. It was shown that the hematite sample under study is a good sorbent for removal of divalent copper ions from aqueous solutions. The process of Cu2+ sorption is described by the Langmuir equation. The parameters of this equation were determined at various pH values of the model solution and compared with similar published parameters for other hematite samples.
