Comparative Experimental Study on an Endocrine Disruptor Degradation by UV/H2O2 and UV/H2O2/TiO2 Systems

Bisphenol A (BPA) � an endocrine disruptor, degradation was studied using the following systems: UV/H2O2 and UV/H2O2/TiO2. Optimum operating conditions were established for both studied systems and experimental results showed that the two systems could be successfully used for advanced degradation of BPA achieving degradation efficiencies for BPA of 99.99% in optimum working conditions. The two systems were compared and both advantages and disadvantages of each system were identified. Nine degradation intermediates were identified for BPA degradation in UV/H2O2/TiO2 system and a possible degradation pathway was proposed.
