The potentiometric response behavior of a polypyrrole(PPy) coated Pt electrode to nitrate ion has been studied. The electrode shows a nernstian behavior with a slope of 59 mV over 0.50 M to and a detection limit of . The response of the electrode is fast and the selectivities for are found to be improved. The effect of pH on the potential response to is compared with the existing nitrate ion selective electrodes.
