Chemical disinfection factor – chlorine dioxide

In the family of chemical disinfection, chlorine dioxide stands out with its high efficiency and safety, becoming a popular disinfection factor. Today, we will take you to learn more about its preparation method, disinfection application and precautions for use.

1. Preparation method: scientifically proportioning to produce a “disinfection expert”

Chlorine dioxide is mainly prepared by chemical method and electrolytic method. The chemical method often uses sodium chlorate to react with hydrochloric acid, and generates chlorine dioxide gas by precisely controlling the ratio of reactants and reaction conditions; the reaction of sodium chlorite with chlorine is also a common chemical preparation method. The electrolytic method uses an electrolytic device to use salt as raw materials to produce chlorine dioxide under specific voltage and current conditions. The chemical method is widely used, and the electrolytic method is relatively more environmentally friendly. Both methods have their own advantages.

2. Disinfection methods: multiple scenarios “show their prowess”

In drinking water disinfection, chlorine dioxide can effectively kill bacteria, viruses and algae in the water, and will not produce harmful byproducts, ensuring drinking water safety; disinfection of surfaces in hospital environments and public places can quickly eliminate pathogenic microorganisms by spraying or wiping chlorine dioxide solution; in the food processing industry, it can also be used for fruit and vegetable cleaning, equipment disinfection, and extending the shelf life of food. Whether it is gaseous or liquid chlorine dioxide, it can play a powerful disinfecting role in different scenarios.

3. Precautions: Safe use is the key

Although chlorine dioxide is good, it should be used with caution. It has strong oxidizing properties and should be avoided from contact with grease, organic matter, etc. to prevent violent reactions; personal protection must be done when using it, and gloves, masks and goggles must be worn to prevent the solution from splashing on the skin and eyes; when storing, it should be placed in a cool, ventilated, light-proof place, away from fire and heat sources; at the same time, it should be used strictly in accordance with the prescribed concentration and time to avoid the harm caused by excessive disinfection.

Chlorine dioxide has built a solid line of defense for our health. Only by mastering its key points of use can this “disinfection star” better serve our lives. Don’t forget these knowledge next time you use chlorine dioxide!
