We have compared the elimination of 5-bromosalicylic acid (BSA) in the systems of goethite (α-FeOOH)/H2O2 and lepidocrocite (γ-FeOOH)/H2O2. The results demonstrated that BSA (10 mg L-1) could be successfully adsorbed on α- and γ-FeOOH (0.5 g L-1) and then effectively degraded after the addition of H...
