This work describes the development of a bicomponent nanostructured Ti/TiO2/WO3 electrode prepared by template method and investigates its efficiency in a photoelectrocatalytic method by using visible light irradiation and applied potential of 1V. After 2h of treatment there are reduction of 97% discoloration, 62% of mineralization and formation of three byproducts assigned as: 2-amine-5-sulfo-benzoic acid, 2,3-dioxo-14-indole-5-sulfonic acid, and 2-amino-α-oxo-5-sulfo-benzeneacetic acid were identified by HPLC-MS/MS. But, cytotoxicity was completely removed after 120min of treatment. © 2013 Elsevier Ltd.586-593engByproductsCytotoxicityFood dyeGenotoxicityIndigo carminePhotoelectrocatalytic treatmentGenotoxicitiesIndigo CarmineNano-structured electrodesPharmaceutical industryPhotoelectrocatalyticVisible-light irradiation2 amine 5 sulfo benzoic acid2 amino alpha oxo 5 sulfo benzeneacetic acid2,3 dioxo 14 indole 5 sulfonic acidacidindigo carminenanomaterialtitaniumtitanium dioxidetungstentungsten trioxideunclassified drugacetic acidanatasedrugdyeelectrodeirradiancepollutant removaltoxicityvisible spectrumcell strain HepG2controlled studycytotoxicitygenotoxicityhigh performance liquid chromatographyhumanhuman cellirradiationmass spectrometrymineralizationphotocatalysisElectrodesIndolesModels, ChemicalNanostructuresOxidesPhotochemical ProcessesTitaniumTungstenWater Pollutants, ChemicalWater PurificationArtigo10.1016/j.chemosphere.2012.12.027WOS:000318208500003Acesso restrito2-s2.0-848758049680000-0002-2296-1393
