Abstract

In this study, a polypyrrole (ppy) electrode was prepared, the best potential and sensitivity to hydrogen peroxide of this electrode were determined, electrochemically. For this purpose, polypyrrole was deposited by electropolymerization of pyrrole at a scanning speed of 50 mV/s between 0.0 - +0.7 V potential range by using cycling voltammetry (CV) technique on the surface of  0.5 cm2 platinum (Pt) plate. Platinum/polypyrrole electrode was prepared by adding 0.1 M H2SO4 solution to the coating medium. The sensitivity of this electrode to hydrogen peroxide was determined using 0.025 M phosphate buffer at pH and optimum conditions were investigated. Working potential was determined as 0.7 V and pyrrole concentration was also 0.2 M ppy.
