    Author: Li C, Gao NY, Zhang KJ.
    Journal: Huan Jing Ke Xue; 2009 Mar 15; 30(3):771-4. PubMed ID: 19432326.
    Abstract:
    The degradation of bispehnol A (BPA) in aqueous suspension by interaction of photocatalytic oxidation and ferrate (VI) oxidation was investigated under different conditions. The results indicate that the formation of Fe (V) and Fe (IV) is in the photoreduction of Fe (VI) by electron (e(cb)-) on the surface of TiO2. The oxidation efficiency of the photocatalytic oxidation in the presence of Fe (VI) is much greater than that without Fe (VI). In addition, the decomposition of Fe (VI) under different conditions was also investigated. The results indicate that the Fe (VI) reduction is enhanced by photocatalytic oxidation and the adsorption capacity of Fe (VI) at TiO2 surface decreases with pH increase. When the photocatalytic oxidation is used to degrade BPA, Fe (VI) could increase the degradation rate about 2.5 times.
