| Abstract: | Hypochlorous acid solution, which can be used for disinfection in daily life, have been prepared continuously using a convenient electrochemical device. The disinfection effect of the prepared hypochlorous acid solution was found to be closely related to the electrolysis conditions. Based on the relationship among the disinfection efficiency of hypochlorous acid solution, the available chlorine concentration and the pH, the effects of varying the concentration, pH of NaCl solution and the current density on the current efficiency and the disinfection capacity of the resulting solution were investigated. The hypochlorous acid solution prepared under optimized conditions showed excellent sterilizing effect for killing colibacillus in 30 seconds and the Staphylococcus aureus in 2 minutes. |
