Hydrogen peroxide, which is widely used as an oxidizing agent for disinfection, could be increased in oxidizing power by synergy with organic acids. In this study, citric acid was used as an organic acid. The increased oxidizing power was confirmed by the potentiometry, and the cyclic voltammetry was used for confirming the reduction potential change and oxidation current disappearance of hydrogen peroxide. The non-ideal behavior of hydrogen peroxide titration with permanganate and of citric acid titration with hydroxide were observed. The disinfection power using the mixture was confirmed by a 5 minute contact disinfection test of harmful bacteria (Escherichia coli and Staphylococcus aureus), in which the concentrations of citric acid and hydrogen peroxide were <400 and <500 ppm, respectively.
