Development of a device to provide electrolyzed water for home care

Abstract

Strongly acidic electrolyzed water (SAEW) is readily prepared from water containing NaCl by direct current electrolysis. SAEW has a strong bactericidal activity due to the high available chlorine (AC) concentration. We developed a compact device with a titanium-coated platinum electrode to make electrolyzed water for home care and evaluated this device. Analysis of the electrolyzed water produced by the device confirmed that the water on the anode side conformed to the definition of SAEW and it had a strong bactericidal activity. This device is useful for making SAEW as a disinfectant to employ at home care, when considering economic and environmental factors, since it returns to ordinary water after use. © 2008 Springer-Verlag.
