Problems solved by technology

[0006] 2. During the disinfection process of strongly acidic chlorine dioxide disinfectant, as the acidity decreases (pH value increases), the balance of chemical reactions will change, and chlorite will be regenerated, which will increase the toxic and side effects of the disinfectant and disinfection costs
[0007] 3. The reaction is reversible and needs to be carried out in a strongly acidic medium, so the disinfectant is highly acidic and highly corrosive, which is not conducive to the application of disinfectant
[0008] 4. When disinfecting water bodies, chlorine dioxide has strong oxidizing properties, poor stability, and short disinfection time in water.

Abstract

The invention discloses a disinfectant containing the component of chlorine dioxide. The disinfectant is a water solution configured by chlorite and trichloro isocyanuric acid at the weight ration of 1:0.5 to 1:1.5. The concentration of the chlorite in the water solution is 0.1 percent to 10 percent. The configuring method is carried out as steps that: a. the chlorite is made into a solution with concentration of 0.1 percent to 10 percent; b. the trichloro isocyanuric acid is added into the chlorite solution and then agitated; c. the compound solution of the chlorine dioxide and the dichlord isocyanurice acid is generated.

Description

Technical field: [0001] The invention relates to the field of chemical disinfectants, in particular to disinfectants containing chlorine dioxide. Background technique: [0002] Chlorine dioxide disinfectant is a disinfectant that produces less toxic and side effects in water. It is usually obtained by reacting chlorite with acidic substances such as sulfuric acid and hydrochloric acid. This method of obtaining chlorine dioxide disinfectant has the following disadvantages: [0003] 1. The conversion rate of the reaction is low. The reaction between chlorite and acidic substances is a disproportionation reaction. Some chlorite does not generate chlorine dioxide. The reaction formula is as follows: [0004] 5ClO 2 - +4H + 4ClO 2 +2H 2 O+Cl - [0005] As can be seen from the above formula, theoretically, only 80% of chlorite ions may be converted into chlorine dioxide by chemical reaction. [0006] 2. During the disinfection process of strongly acidic chlorine dioxide d...
