Bisphenol A is an endocrine disruptor. Complete mineralization of bisphenol A is therefore a primary environmental issue.
Here, the combination of ozonation and photocatalysis by TiO2 is proposed for the degradation and final mineralization of bisphenol A. TiO2 films deposited onto two sides of an Al lamina show good stability and high surface roughness. We used a specific experimental
setup employing two facing ultraviolet lamps and TiO2 layers, together with an ozone flux. High-performance liquid chromatography–mass spectrometry determinations on bisphenol
A solutions sampled at different reaction times and Fourier Transform Infrared analyses of the oxide at the end of the reaction
were performed to study the reaction intermediates and the overall degradation mechanism. Our results show that pollutant
mineralization achieved with the combined method is far higher, of 55% in the case of 0.3 mM bisphenol A, than those obtained
by individual treatments such as photolysis (<3%), ozonation (6%), photocatalysis (6%), and by other combined processes: photolytic
ozonation (13%) and catalytic ozonation (15%). This finding is explained by the occurrence of highly synergistic effects. 相似文献
