Europium-doped manganese tungstate for dual electrocatalytic activity
Abstract
Ethidium bromide (EthBr) is a fluorescent dye commonly used in molecular biology for visualization of DNA in electrophoresis gels. As EthBr intercalates nucleic acids, it is a potential human mutagen. Therefore, an efficient method for its removal would be beneficial to human and environmental safety.
Europium(III)-doped manganese tungstate was synthesized and characterized. The Eu-doped MnWO4 and modified carbon paste electrodes (CPE) containing different amounts of this material were characterized. These electrodes were used for electrochemical determination and degradation of EthBr.
Firstly, EthBr was characterized electrochemically by cyclic voltammetry using a glassy carbon electrode and the different CPEs, at different conditions. Then, the optimal method for voltammetric EthBr determination using the modified CPE was investigated. It was found that SWV gives the best results.
Lastly, the material was applied to graphite rods as electrodes for electrochemical oxidative removal... of EthBr from aqueous solution and the optimal parameters for the process were established. The resulting degradation products were determined. The devised method gave satisfying results for dye removal, with complete decolorization after 50 minutes of treatment.
