Online electrochemical flow sensor for monitoring an electron mediator [Co(I)(CN)5]4- during its generation and pollutant removal |
| 초록 |
Electrochemically generated electron mediator quantification is still ex-situ with indirect titration method. The present work aims to develop a suitable electrode in flow sensor cell to monitor electrogenerated [Co(I)(CN)5]4- during electrolysis and its use in pollutant removal. First, suitable potential window for each electrode (Pt, carbon, Au, Ag) was derived using cyclic voltammetry under flow condition (solution slow rate between 0.5 to 3.0 L/min). The limiting potential change with electrolysis time was compared with chemically prepared [Co(I)(CN)5]4-and potentiometric titration values to make calibration plot that was used to monitor the electron mediator concentration. The optimized method was also used to monitor the [Co(I)(CN)5]4- concentration during air pollutant removal. |
