Destruction of phenol by mediated electrochemical oxidation using combined cerium – silver redox couple in nitric acid medium |
| 초록 |
Mediated electrochemical oxidation (MEO) is one of the important sustainable processes for organic pollutant destruction and has been tested by many researchers. In the MEO a metal ion capable of exhibiting redox behavior is oxidized from lower oxidation state to higher oxidation state by an electrochemical cell and used for mineralizing the toxic organics into CO2 and water. In this study silver - cerium mediated electrochemical oxidation of phenol was carried out. The current efficiency for the electro-oxidation of cerium(III) in nitric acid was found to be increased by the addition of silver ions. This mixed mediator system was tested for the oxidation of phenol in order to optimize the parameters for organic pollutant destruction. The mineralization efficiency calculated based on the CO2 evolution was found to be higher for silver - cerium mediated oxidation compared to the non-silver system at low temperature. |
