Problems solved by technology

[0003] Chlorine dioxide has strong oxidizing properties, and it will be explosive if the volume concentration in the air exceeds 10%, but its aqueous solution is very safe; due to the explosion hazard of chlorine dioxide gas, when compressing or storing chlorine dioxide, whether it is alone or Combination with other gases has not been commercially successful, so chlorine dioxide must be produced at the point of use and used immediately, that is, ready-to-use
In the process of releasing chlorine dioxide, the phenomenon is that the concentration of chlorine dioxide produced is relatively high at the beginning, and as the reaction proceeds, the concentration of chlorine dioxide released begins to decrease, resulting in inconsistent concentrations before and after, and the concentration of chlorine dioxide Efficiency cannot be guaranteed. At the same time, the residual waste liquid may also cause secondary pollution, and it is limited in time and space. It can only be used and prepared in a short period of time. It is difficult to completely disinfect dead corners or complex environments.

Abstract

The invention discloses a chlorine dioxide disinfectant which comprises chlorine dioxide, deionized water and a stabilizer. The chlorine dioxide disinfectant is free from being activated, with a shelf life of one year, and disinfection and sterilization functions. The invention further discloses a preparation method of the chlorine dioxide disinfectant. The method is simple and in large-scale production.

Description

technical field [0001] The invention belongs to the field of chemical disinfectants, in particular to a chlorine dioxide disinfectant and a preparation method thereof. Background technique [0002] Chlorine dioxide is a broad-spectrum, highly effective sterilant. Many foreign research results show that chlorine dioxide can kill many pathogenic bacteria such as Escherichia coli and Staphylococcus aureus at an extremely low concentration (0.1ppm). Even under the interference of organic matter, when the concentration is tens of ppm, it can completely kill all microorganisms such as bacterial propagules, hepatitis viruses, bacteriophages and bacterial spores. [0003] Chlorine dioxide has strong oxidizing properties, and it will be explosive if the volume concentration in the air exceeds 10%, but its aqueous solution is very safe; due to the explosion hazard of chlorine dioxide gas, when compressing or storing chlorine dioxide, whether it is alone or Combining with other gases...
