dc.description.abstractMethyl orange from water was removed by photocatalytic anodic oxidation using a titanium dioxide array surface. The coating was prepared by anodizing a titanium plate in an ethylene glycol electrolyte-containing NH4F followed by heat treatment to realize a photocatalytic surface under UV light. Scanning electron microscopy imaging showed that the array coating consisted of closely spaced nanotubes perpendicular to the titanium plate. The aqueous solution of methyl orange was circulated through a rectangular channel flow cell containing the coated anode. The effects of electrolyte flow rate and applied potential on the oxidation rate and efficiency were evaluated. At higher mean linear flow rates, the efficiency of the oxidation process improved, indicating a mass transport-controlled process. At more positive applied potentials, the TiO2 structure deteriorated resulting in a lower oxidation efficiency.en
