Abstract

The invention relates to the field of sterilization and disinfection and particularly relates to a sterilization solution and a preparation method thereof. The preparation method of the sterilization solution, disclosed by the invention, comprises the following steps of: (1) providing an effective bromine providing unit containing effective bromine or being capable of producing the effective bromine; (2) providing a pH value regulating unit; and (3) mixing the pH value regulating unit with the effective bromine providing unit to obtain the sterilization solution, wherein the pH value of the sterilization solution is 2-9, the content of the effective bromine in the sterilization solution is not lower than 1mg / L, and the electric conductivity is not higher than 120S / m. Compared with the existing sterilization solution containing the effective bromine, the sterilization solution prepared by the preparation method of the sterilization solution containing the effective bromine can reduce the corrosion against metal and further expand the range of applications.

Description

technical field [0001] The invention relates to the field of sterilization and disinfection, in particular to a bactericidal solution and a preparation method thereof. Background technique [0002] Available bromine has strong oxidizing properties, and the oxidation-reduction potential value of its aqueous solution is usually not lower than 500mV, so it shows a very strong effect of killing microorganisms. [0003] Due to the different distribution of hydrogen ions, potassium ions, and sodium ions inside and outside the microbial biofilm, there is a certain potential difference between the inside and outside of the membrane when the potential reaches a dynamic equilibrium, generally about -700 ~ +900mV. Factors such as oxidizing and reducing substances and pH in the bactericidal solution containing available bromine make it have a high ORP (that is, ORP>500mV). The strong oxidizing bactericidal solution quickly captures electrons after contacting microorganisms, disturbs...
