Electrochemical Degradation of the Reactive Red 141 Dye on a β-PbO2 Anode Assessed by the Response Surface Methodology
A degradação eletroquímica do corante Vermelho Reativo 141 foi investigada por meio da aplicação da metodologia de superfície de respostas, utilizando reator filtro-prensa com anodo de β-PbO 2 . A carga requerida para 90% de descoloração (Q) e a remoção da demanda química de oxigênio após 30 min de eletrólise (COD) foram utilizadas para modelar o sistema. As variáveis investigadas foram a densi...
متن کاملSonoelectrochemical mineralization of perfluorooctanoic acid using Ti/PbO2 anode assessed by response surface methodology
BACKGROUND Perfluorocarboxylic acids (PFCAs) are emerging pollutant and classified as fully fluorinated hydrocarbons containing a carboxylic group. PFCAs show intensively resistance against chemical and biological degradation due to their strong C-F bond. The Sonoelectrochemical mineralization of the synthetic aqueous solution of the perfluorooctanoic acid (PFOA) on Ti/PbO2 anode was investigat...
متن کاملA COMPARISON OF ELECTRODEPOSITED Ti/β-PbO2 AND Ti-Pt/β-PbO2 ANODES IN THE ELECTROCHEMICAL DEGRADATION OF THE DIRECT YELLOW 86 DYE#
The electrochemical performance of electrodeposited Ti/β-PbO 2 and Ti-Pt/β-PbO 2 anodes was galvanostatically evaluated (batch mode, 50 mA cm) to degrade the Direct Yellow 86 dye (100 or 200 mg L in 0.1 mol L Na 2 SO 4 + 1.5 g L NaCl), investigating the effect of pH and temperature. Similar results were obtained for both electrodes and the best conditions for removal of color and chemical oxyge...
متن کاملInvestigation of affecting operational parameters in photocatalytic degradation of reactive red 198 with TiO2: optimization through response surface methodology
Dye-containing wastewater generated from textile industries is a major source of environmental pollution. Azo dyes, which are the largest group of coloring agents, are widely used in industries.This research investigated the photocatalytic decolorization and degradation of an azo dye Reactive Red 198 (RR198) in aqueous solution with TiO2-P25 (Degussa) as photocatalyst in slurry form using UV li...
متن کاملApplication of response surface methodology to optimize the ultraviolet/hydrogen peroxide process for the removal of Reactive Red 195 dye from aqueous solution
Background and Objective: The most used dyes in textile industries are Azo Group dyes. Azo dyes have complex aromatic compounds, low chemical and biodegradable stability. Due to these properties, treatment of this type of wastewater by conventional methods will not meet environmental standards. The advanced oxidation process has been widely used to treat organic matter from wastewater. In this ...
