Dye destruction and simultaneous generation of sodium hydroxide using a divided electrochemical reactor / S. Raghu in Industrial & engineering chemistry research, Vol. 47 n°15 (Août 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°15 (Août 2008) . - p. 5277–5283 Titre : Dye destruction and simultaneous generation of sodium hydroxide using a divided electrochemical reactor Type de document : texte imprimé Auteurs : S. Raghu, Auteur ; C. Ahmed Basha, Auteur Année de publication : 2008 Article en page(s) : p. 5277–5283 Note générale : Bibliogr. 5282-5283 Langues : Anglais (eng) Mots-clés : Textile  dye;  Dye  --  Degradation;  Electrochemical  proces Résumé : Textile dye bath effluent contains high concentrations of organic dye, sodium chloride, and other chemicals which inhibit the activity of microorganisms during biological oxidation. Hence high concentrations of organic dye and total dissolved solids have to be removed considerably before biological treatment. In this paper, degradation of dye effluent and simultaneous generation of caustic soda in an electrochemical membrane cell was investigated. Experiments were carried out at different current densities and different flow rates using Ti/RuO2/IrO2 as anode and stainless steel as cathode. In the present study of dye effluent treatment the results showed that the electrochemical process could effectively remove COD and color by anodic oxidation (92.16% and 100%) and concentrate caustic soda from 40 to 210.28 g L−1.
