Amperometric determination of hydrogen peroxide using a copper microelectrode

Abstract

The cathodic reduction of hydrogen peroxide at copper microelectrodes was investigated in phosphate buffer solutions. Following the optimization of the experimental conditions, the proposed sensor presented excellent analytical properties for the amperometric detection of hydrogen peroxide at −0.2 V vs. Ag/AgCl (saturated KCl). The usefulness of the fabricated electrochemical sensor was confirmed by the determination of hydrogen peroxide in commercial products and the values obtained by the proposed method agreed well with those found by using a standard method.
