Abstract

The invention relates to the field of sterilization and disinfection and particularly relates to a peracetic acid solution and a preparation method thereof. The preparation method of the peracetic acid solution, disclosed by the invention, comprises the following steps of: (1) providing a peracetic acid providing unit containing peracetic acid or being capable of producing the peracetic acid; (2) providing a pH value regulating unit; (3) mixing the pH value regulating unit with the peracetic acid providing unit to obtain the peracetic acid solution, wherein the pH value of the peracetic acid solution is not more than 9.0, the content of the peracetic acid in the peracetic acid solution is not lower than 1mg / L and the electric conductivity is not higher than 120S / m. Compared with the existing solution containing the peracetic acid, the peracetic acid solution disclosed by the invention 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 peracetic acid solution and a preparation method thereof. Background technique [0002] Peracetic acid has strong oxidizing properties, and therefore, exhibits 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 solution containing peracetic acid make it have a high ORP (ie ORP>600mV). The strong oxidizing peracetic acid solution quickly captures electrons after contacting microorganisms, disturbs the balance of the biofilm, changes the potential difference inside and outside the biofilm, and the osmotic ...
