Problems solved by technology

Because chlorine dioxide is very active and unstable, it can be made into an unstable aqueous solution. It is sensitive to light and heat. It has a dissociation rate of about 2% to 10% per day at room temperature. It is not easy to store and transport, and due to dissociation and Volatilization affects the disinfection effect of chlorine dioxide aqueous solution
[0003] At present, what is more commonly used is to pass chlorine dioxide into the stable absorption liquid, generally composed of sodium carbonate or sodium percarbonate and hydrogen peroxide (patent No.: CN100441499C, CN1235913C) or add sodium hydroxide to form an alkaline solution (patent No. : CN103101883B), chlorine dioxide exists in the form of chlorite, and the stability of chlorite solution itself is relatively poor, and needs to be activated during use; extremely inconvenient to use

Description

technical field [0001] The invention belongs to the fields of medicine, sanitation and epidemic prevention technology, aseptic technology, bioengineering, disinfection and sterilization, and environmental protection technology, and specifically relates to a chlorine dioxide composite material and a preparation method and application thereof. Background technique [0002] Chlorine dioxide is extremely soluble in water, and its solubility in water is five times that of chlorine gas. In the disinfection process, chlorine dioxide is usually used in the form of aqueous solution for easy handling. Because chlorine dioxide is very active and unstable, it can be made into an unstable aqueous solution. It is sensitive to light and heat. It has a dissociation rate of about 2% to 10% per day at room temperature. It is not easy to store and transport, and due to dissociation and Volatilization affects the disinfection effect of chlorine dioxide aqueous solution. [0003] At present, w...
