Abstract

The invention relates to the field of sterilization and disinfection, and particularly relates to low corrosive oxidation potential sterilization water and a preparation method thereof. The preparation method of the low corrosive oxidation potential sterilization water comprises the following steps: (1) providing an available chlorine provision unit which contains available chlorine or can generate available chlorine; (2) providing a pH value regulation unit; and (3) mixing the pH value regulation unit and the available chlorine provision unit to obtain a strong oxidizing solution, wherein the pH value of the strong oxidizing solution is 2-8, the oxidation-reduction potential is not lower than 600 mV, the available chlorine content is not lower than 3 mg/L, and the sum of the 2-methylpropanoic acid content and the 2-methylpropionate ion content is not higher than 1.8 mol/L. Compared with the existing acidic oxidation potential sterilization water, the sterilization water prepared by the oxidation potential sterilization water preparation method can reduce the corrosion to metal, thereby widening the application range.

Description

Technical field [0001] The invention relates to the field of sterilization and disinfection, in particular to a low-corrosive oxidation potential sterilization water and a preparation method thereof. Background technique [0002] The concept of oxidation-reduction potential introduced in the field of disinfection is derived from the acidic oxidizing potential water generator developed and produced by Japan in the 1980s and the acidic oxidizing potential water produced by the generator. Acidic oxidation potential water (abbreviation: EOW) refers to water with high oxidation-reduction potential (ORP), low pH and low concentration of available chlorine (ACC). [0003] The mechanism of acidic oxidizing potential water sterilization is as follows: [0004] First of all, most types of microorganisms in nature live in an environment of pH 4-9, and the pH value of the acidic oxidizing potential water can affect the charge on the microbial biofilm and the absorption of nutrients and enzyme a...
