Preparation of Iodine Doped Titanium Dioxide to Degrade Aqueous Bisphenol A

Article Preview

Abstract:

Degradation of aqueous bisphenol A (BPA) using photocatalysts of granular iodine doped titanium dioxide (I-doped TiO2) under various irradiations (365 or 410 nm) was investigated. The degradation effect of aqueous BPA using I-doped TiO2 photocatalysts (iodine/titanium = 0.5 mole %) were 93 and 100 % under two irradiations of visible and UV light. This result indicated that I-doped TiO2 photocatalysts of were achieving energy-saving. In addition, the BPA removal rate satisfies pseudo-first-order kinetics and the degradation of BPA was evident after five cycles, indicating the stability and reusability.
