제목 Development of electrochemical in-situ flow sensor for electrogenerated electron mediator identification during electrolysis
초록 To overcome the off-line potentiometric titrations for electron mediator’s quantification, in-situ determination has been attempted. Here in, we have initiated to monitor the electrochemically prepared mediator [Co(I)(CN)5]4- by in-situ flow sensor cell coupled with paired electrolysis cell. First, cyclic voltammetry peak current for a standard redox couple Fe(II)/Fe(III) with different concentration ratios was used in the flow sensor cell to check the developed method. Then the Chemically prepared [Co(I)(CN)5]4- in presence of 10 M KOH at different concentrations were analyzed by UV-Visible and potentiometric titration method and compared. Finally, the chemically prepared different concentration of Co(I) do monitored using selected electrode under the inert atmosphere by flow sensor cell. The concentration of [Co(I)(CN)5]4- was derived from the calibration plot.
