Abstract
Efficacy of surface sterilization and physicochemical properties of electrolyzed water manufactured depending on electrolyte, materials, and type of electrolytic diaphragm used were investigated. Physical properties of electrolyzed water manufactured from diaphragm system showed the highest effectiveness under at distance between diaphragms of 1.0 mm and 20% NaCl supplying rate of 6 mL/min. ORP, HClO (should defined) content, and pH at above conditions were 1,170 mV, 100 ppm, and 2.5, respectively. Two-stage electrolyzed system was more effective than one-stage one. Electrolyzed water manufactured from non-diaphragm system at 4 mL/min supplying rate of 20% NaCl was similar to the most effective diaphragm system, whereas ORP, HClO content, and pH were 800 mV, 200 ppm, and 9, respectively. Sealed electrolyzed water could be preserved more than one month at room temperature with ORPs of 750 and 1,150 mV in non-diaphragm and diaphragm systems, respectively, and at HClO content of 100 ppm. Physicochemical properties of electrolyzed water manufactured from electrolytic diaphragm of $IrO_{2}$ and Pt+Ir were more effective than that of Pt. ORP and HClO contents of electrolyzed water manufactured from various electrolytes were high in order of NaCl>KCl>$CaCl_{2}$, whereas no differences were observed among electrolytes in sterilization efficacy. Twelve kinds of microorganisms tested (initial total count, $10^{5}-10^{6}CFU/mL$) were sterilized within 1-2 min by electrolyzed water.
