| Resumo : | Photoelectrodes were used to treat synthetic textile wastewater contaminated with indanthrene blue dye. Two media of treatment were used (NaCl and Na2SO4), with variations on temperature, pH, current density, dye and chloride concentration. A modified Pechini method was applied to obtain Ti/Ru-based electrodes (Ti, Ru, Ti0.5Ru0.5, Ti0.75Ru0.25 and Ti0.25Ru0.75) containing anatase TiO2 nanoparticles and a color degradation analysis was done. Physical (atomic force microscopy and X-ray diffractometry) and electrochemical characterizations (cyclic voltammetry) were considered. The condition that yielded highest color removal for the system presented 0.05 mol L−1 NaCl, 100 mA cm–2, 35 °C and pH 7, independent of the dye concentration for the Ti0.25Ru0.75 electrode. |
| Abstract: | Fotoeletrodos foram usados para tratar efluentes têxteis sintéticos contaminados com corante azul indantreno. Dois meios de tratamento foram usados (NaCl e Na2SO4) com variações de temperatura, pH, densidade de corrente, concentrações de corante e de cloreto. Um método de Pechini modificado foi aplicado para obter os eletros de Ti/Ru (Ti, Ru, Ti0.5Ru0.5, Ti0.75Ru0.25 e Ti0.25Ru0.75) contendo nanoparticulas de TiO2 anatase e a análise de degradação de cor foi realizada. Caracterizações física (microscopia de força atômica e difratometria de raios X) e eletroquímica (voltametria cíclica) foram feitas. As condições que geraram maior remoção de cor para o sistema apresentado foram NaCl 0,05 mol L−1, 100 mA cm–2, 35 ºC e pH 7, independente da concentração de corante para o eletrodo de Ti0.25Ru0.75. |
