Hydrodynamic methods RDE and flow cell comparative analyses for effective in-line potentiometric sensor for electrogenerated mediator |
| 초록 |
Our recent publication unfolded an in-line determination of homogeneous electron mediator but, validation by a standard hydrodynamic method is still deserved. In the present investigation, a comparative analysis by RDE (rotating disc electrode) and flow cell methods were optimized in development of on-line potentiometric sensor for homogeneous electron mediator generation. First, [Co(I)(CN)5]4- (Co(I)) was electrochemically generated in 10 M KOH solution by Nafion324 membrane divided electrochemical cell. The electrogenerated solution monitored by current and potential using RDE and flow cell with different RPM (rotation per minute) and flow rate by cyclic voltammetry (CV) method. By comparing the peak potential and peak current change, validation of a suitable method was derived for potentiometric sensor in determination of homogeneous electrogenerated electron mediator. |
