Determination of Adequate pH of Electrolyzed Acidic Water for Disinfection, Under Consideration of Sub-Effective Corrosion Against Metals

Dai Yoshizawa, Hideki HAYASHI, Motoki SOGO, Kouichi Sano et autres

Electrolyzed acidic water (EAW) is one of the most commonly used disinfectants. EAW has sufficient bactericidal efficacy; however, it corrodes instruments in clinical settings. The component that significantly contribute to the bactericidal efficacy of EAW is hypochlorous acid (HClO). According to the …
