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.
