다국어 초록 (Multilingual Abstract)

In the present investigation, Ag and Ag-Ni or Ag-Co metal ions coated Nafioni324 membrane electrode divided cell was developed and compared in amperometric detection of air pollutants. Ag and Ag-Ni or Ag-Co were chemically coated on the Nafion324 membrane and used in filter press technique to make a cell with one side having 0.1 M KOH electrolyte and gas phase cathodic half-cell. Based on the cyclic voltammetry and linear sweep voltammetry analyses, 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.
