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 3-methylbutyric acid content and the 3-methylbutyrate 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-corrosivity oxidation potential sterilization water and a preparation method thereof. Background technique [0002] The concept of introducing redox potential in the field of disinfection originated from the acid oxidation potential water generator developed and produced in Japan in the 1980s and the acid oxidation potential water produced by the generator. Acid Oxidation Potential Water (abbreviation: EOW) refers to water with high oxidation reduction potential (ORP), low pH characteristics and low concentration of available chlorine (ACC). [0003] The mechanism of acid oxidation 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 acidic oxidation potential water can affect the charge on the microbial biofilm, the absorption of nutrients, the activity...
