Mediator precursor contained electrolyte in a half-cell on detection of online air pollutant during its electrochemical removal |
| 초록 |
Instead of only electrolyte in one half-cell in detection gas sensors, addition of mediator precursor can be an added advantageous to reduce the over potential. In the present investigation, 0.1 M CoSO4 in 5 M H2SO4 or 0.05 M [Ni(CN)4]2- in 10 M KOH as electrolyte in one half-cell were used with Ag-Ni or Ag-Co metal ions coated Nafion324 membrane electrode divided cell for detection of air pollutants. Based on the cyclic voltammetry and linear sweep voltammetry analyses with and without CoSO4 and [Ni(CN)4]2-, the gas phase redox peak was fixed for detection of selected gas pollutants. Then sense a selected air pollutants by amperometric method at different suitable applied voltage. The current with different feed concentration were compared with in-situ FTIR gas analyzer concentration and derived calibration plot. |
