Problems solved by technology

Therefore, chlorine-containing disinfectants cannot be stored for a long time after being dissolved and diluted, and are inconvenient to use
[0007] (2) Hypochlorous acid molecules decompose in water to release gas Cl 2 , gas Cl 2 Not only pollute the environment, but also cause tearing, coughing, irritation of the skin and mucous membranes, and in severe cases, poisoning, suffocation and death
Therefore, chlorine-containing disinfectants are generally not suitable for indoor air disinfection.
[0008] (3) Chlorine-containing disinfectant is a kind of high-efficiency disinfectant, which has strong irritation and is generally not suitable for disinfection of human skin and mucous membranes.
The disadvantage of this method is: the disinfection ability of the prepared disinfectant is greatly affected by the pH value of the system. When the pH value of the system increases after several times of dilution, the disinfection ability will obviously decrease; the stable period is generally less than one year; A large amount of acid compounds will irritate the skin and affect its application range

Embodiment 1

[0023] Example 1: Weigh 15g of nonylphenol polyoxyethylene ether ammonium sulfate and 10g of polyvinylpyrrolidone, dissolve in 500 ml of purified water at a temperature of 50°C, and then add 9g of sodium dichloroisocyanurate (containing 63% available chlorine) After it is fully dissolved, add 10g of amine sulfamate; finally dilute to 1 liter with purified water. The available chlorine concentration of the prepared chlorine-containing disinfection water is 0.53%. It is stored for 180 days under the condition of being closed and not protected from light, and the available chlorine concentration is 0.49%.

Embodiment 2

[0024] Example 2: Weigh 3 g of nonylphenol polyoxyethylene ether ammonium sulfate and 2 g of polyvinyl pyrrolidone, dissolve them in 200 ml of purified water at a temperature of 50° C., and then add 2 g of sodium dichloroisocyanurate (containing 63 percent available chlorine), After it is fully dissolved, add 2 g of amine sulfamate, and finally, dilute to 1 liter with pure water. The available chlorine concentration of the prepared chlorine-containing disinfection water is 0.11%. It is stored for 180 days under the condition of being closed and not protected from light, and the available chlorine concentration is 0.11%.

Embodiment 3

[0025] Example 3: Weigh 0.5 g of nonylphenol polyoxyethylene ether ammonium sulfate and 0.4 g of polyvinylpyrrolidone, dissolve them in 100 ml of pure water at a temperature of 50°C, and then add 0.4 g of sodium dichloroisocyanurate (containing available chlorine 63 %), after it is fully dissolved, add 0.5 g of amine sulfamate, and finally dilute to 1 liter with purified water. The available chlorine concentration of the prepared chlorine-containing disinfection water is 0.021%. It is stored for 180 days under the condition of being closed and not protected from light, and the available chlorine concentration is 0.020%.

Abstract

The invention provides a method for preparing a chlorine-containing disinfectant fluid. The chlorine-containing disinfectant fluid comprises a compound complexing agent, a chlorine-containing disinfectant and a stabilizer, wherein the compound complexing agent is a mixture of nonylphenol polyoxyethylene ether ammonium sulfate and polyvinylpyrrolidone; the chlorine-containing disinfectant comprises sodium hypochlorite, trichloroisocyanuric acid and sodium dichloroisocyanurate; and the stabilizer is amino sulfanilic acid. The components are dissolved and diluted in water according to the proportion specified in specifications and the method. The prepared chlorine-containing disinfectant fluid has high disinfecting capability and stable effective chlorine, and can be widely applied in the fields of indoor air disinfection, skin disinfectants and the like.

Description

technical field [0001] The invention relates to the technical field of environmental protection and medical sanitation disinfection, in particular to a preparation method of chlorine-containing disinfection water. technical background [0002] Chlorine-containing disinfectant is one of the most widely used disinfectants, including various types, such as sodium hypochlorite, chloramine-T, trichloroisocyanuric acid, sodium dichloroisocyanurate, etc. Due to the advantages of low cost and high efficiency, chlorine-containing disinfectants are widely used in the fields of drinking water disinfection, environmental disinfection, medical and sanitation disinfection, and are currently the most widely used type of disinfectant in the world. [0003] There are two main dosage forms of chlorine-containing disinfectants: solid dosage form and liquid dosage form. Solid dosage forms have the most types, and the available chlorine content is generally in the range of 20-90%. There are fe...
