Development of in-situ macro electrochemical flow sensor for electrogenerated [Co(I)(CN)5]4- in 10 M KOH: Effect of electrodes on redox potential and current optimization |
| 초록 |
In-situ macro electrochemical sensors at high concentrated electrolyte is still at initla stage. The present work aims to develop a suitable electrode to monitor electrogenerated [Co(I)(CN)5]4- in 10 M KOH solution using a in-situ flow sensor cell. First, suitable potential window for each electrode was derived using cyclic voltammetry under flow condition (solution slow rate between 0.5 to 3.0 L/min). Then suitable scan rate under the flow condition was identified using the selected electrode (Pt, carbon, Cu, Ag). The current at limiting current region or optimum peak region was selected for electrogenerated [Co(I)(CN)5]4- in 10 M KOH solution at suitable electrode. The electrochemically generated Co(I)(CN)5]4- by using potentiometric titration at different electrolysis time was used to make calibration plot that was used to correlate with current value measure using suitable electrode at different electrolysis time. |
