Bisphenol A removal from wastewater using self-organized TIO(2) nanotubular array electrodes.
Chemosphere. 2010 Jan; 78(5):569-75.C

Abstract

Photoelectrocatalytic oxidation of 0.1mM of Bisphenol A (BPA) leads to 100% of degradation monitored by liquid chromatography with diode array optical detection (limit 1microgL(-1)) and 100% TOC removal. Optimum performance was obtained using TiO(2) nanotubular array (NTA) electrodes, grown by anodization of Ti foil in 0.25wt.% NH(4)F and a mixture of glycerol and water (ratio 90:10vol.%) using an applied voltage of 20V for 50h. The effects of supporting electrolyte, pH, applied bias potential and BPA concentration were evaluated as to their effect on the BPA degradation kinetics and the best condition was found to be 0.1M Na(2)SO(4) at pH 6 as supporting electrolyte and applied bias potential of +1.5V vs. Ag/AgCl under UV irradiation. Our findings indicate that TiO(2) NTAs prepared by anodization are versatile and efficient photocatalysts for the degradation of endocrine disruptors.
