عنوان انگلیسی Treatment and Degradation of Azo Dye Waste Industry by Electro-Fenton Process
چکیده انگلیسی مقاله The Electro-Fenton technique was used to investigate the discoloration of carmoisine red azo dye solution. Carbon graphite (cathode) and platinum (anode) electrodes were used to achieve the optimal discoloration efficiency. We examined the effect of Fe2+ concentration and current density. The results showed that with 200 mA/cm2 of electrolysis current and 0.2 mM of Fe2+ at pH = 3; 93% discoloration efficiency was achieved in 60 minutes. IR, LC-MS-MS, and Ion Chromatography studies were used to evaluate the degradation process of carmoisine red. Intermediates of aromatic compounds have been identified. A possible carmoisine red degradation pathway was proposed and discussed.
