Efficiency of different solar advanced oxidation processes on the oxidation of bisphenol A in water

The efficiencies of different solar oxidation processes on the degradation of bisphenol A in water were studied. The work focuses on the removal and mineralization of bisphenol A and the formation of phenolic intermediates.The processes tested were Fe(III) photolysis, ferricarboxylate photolysis, TiO2 photocatalysis, H2O2 photolysis and combinations thereof. The influence of pH and the presence of hematite (α-Fe2O3) on their efficiency, as well as the nature of intermediates formed and development of toxicity were evaluated.
