초록

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 $1.0{\times}10^{-3}M\;NO_3\;^-$ and a detection limit of $1.0{\times}10^{-4}M\;NO_3\;^-$. The response of the electrode is fast and the selectivities for $I^-,\;ClO_4\;^-,\;and\;IO_4\;^-$ are found to be improved. The effect of pH on the potential response to $NO_3\;^-$ is compared with the existing nitrate ion selective electrodes.
