Simultaneous Electroanalysis of Peracetic Acid and Hydrogen Peroxide Using Square-Wave Voltammetry

Abstract

The electrochemical behavior of peracetic acid (PAA) in the presence of hydrogen peroxide (H2O2) has been studied by cyclic and square wave voltammetry. Using gold electrode, two well-separated peaks for the reduction of PAA and hydrogen peroxide were for the first time observed on their cyclic and square-wave voltammograms. The two peaks are utilized in the simultaneous analysis of both species. Good calibration curves were obtained for each species over a wide range of their concentrations.
