Description
Technical Field
The invention relates to the technical field of disinfectants, in particular to a chlorine dioxide disinfectant and a preparation method and application thereof.
Background
Chlorine dioxide is a safe and efficient oxidation type disinfectant, the oxidation capacity of the chlorine dioxide is 2.5 times that of chlorine, during the disinfection process, the chlorine dioxide does not generate substitution reaction with organic matters to produce carcinogenic, teratogenic and mutagenic byproducts such as trichloromethane and the like, and the chlorine dioxide is regarded as a substitute product of the traditional chlorine disinfectant. Has been widely used for drinking water, food production and public environment sanitation and disinfection. Most of the chlorine dioxide disinfectant is a two-component packaging product, and an activating agent needs to be used for activation in advance to generate chlorine dioxide in the using process, so that the chlorine dioxide disinfectant can be diluted and used according to requirements.
At present, the enterprises for packaging drinking water mainly use chlorine dioxide disinfectors or ozone water to disinfect production equipment, packaging containers and other instruments. For example, when a packaged drinking water production enterprise uses chlorine dioxide to sterilize a packaging container, chlorine dioxide is activated firstly, and then the packaging container is diluted according to the using concentration to rinse and sterilize the packaging container, and the using solution can be recycled. However, the existing disinfectant is easy to escape and decompose chlorine dioxide in the using process, has large loss, and is easy to cause the problem of pseudomonas aeruginosa pollution of packaged drinking water caused by unqualified disinfection.
The method is widely used because the purity of the prepared chlorine dioxide is high by using the reaction of chlorite and acid or oxide to generate the chlorine dioxide. The conventional methods using chlorite as a chlorine dioxide generating raw material include an acidification method, an oxychlorination method, a persulfate method, an organic matter or novel complex activation method, and the like. The acidification method is the simplest and easiest method for producing chlorine dioxide by chlorite. The commonly used inorganic strong acids are hydrochloric acid and sulfuric acid, which can react with sodium chlorite quickly to generate chlorine dioxide with high conversion rate, but the chlorine dioxide is lost quickly in the using process, and Cl in the hydrochloric acid - Has a corrosive effect on metals and has use risks. In addition, organic acids such as oxalic acid and citric acid are also used for activating sodium chlorite to generate chlorine dioxide, the organic acids are moderate-strength organic acids and react with sodium chlorite to generate chlorine dioxide, the conversion rate is low, the temperature influence on the generation of chlorine dioxide by the reaction of citric acid and sodium chlorite is large, the content of generated chlorine dioxide is greatly reduced when the environmental temperature is low, and the potential risk is caused to the disinfection of the packaged drinking water industry. And because the conversion rate of chlorine dioxide is low, the content of unreacted sodium chlorite in the disinfectant is high, and the unreacted sodium chlorite can be remained in the container after the packaging container is disinfected, so that the chlorite index in the drinking water is high. Therefore, no matter the strong inorganic acid or the strong organic acid is used for activating the chlorine dioxide, the activated disinfectant has large loss in the dilution and use process, so that the demand of a packaged drinking water production enterprise on the disinfectant is large, and the disinfection cost is increased.
Thus, the need to increase conversion, maintain disinfection efficacy over long periods of time, and reduce risk of use is an urgent problem for the chlorine dioxide disinfectant industry.
