Chlorine dioxide gel and manufacturing method thereof

Abstract

A method for manufacturing chlorine dioxide gel includes the following steps: a step of dissolving peg-copolymer bis-decyltetradeceth in hot water to form an aqueous solution of peg-copolymer bis-decyltetradeceth; a step of heating the aqueous solution of peg-copolymer bis-decyltetradeceth obtained in the above step to form a gel like colloid; a step of dissolving pure chlorine dioxide gas in water to form an aqueous solution of chlorine dioxide; and a step of uniformly mixing the aqueous solution of chlorine dioxide and the colloid of peg-copolymer bis-decyltetradeceth to form a chlorine dioxide gel, whereby with the above steps, a method for manufacturing chlorine dioxide gel that stably preserves chlorine dioxide gas in a gel is provided.

Description

technical field [0001] The invention relates to a chlorine dioxide gel and a preparation method thereof, in particular to a chlorine dioxide gel capable of stably storing chlorine dioxide gas in the gel and a preparation method thereof. Background technique [0002] Chlorine dioxide (Chlorine dioxide, ClO 2 ) The gas itself has an unpaired free active electron, so chlorine dioxide has a strong oxidizing ability and can be used to oxidize proteins, peptides, DNA or RNA of pathogens such as bacteria, viruses, molds, etc. to eliminate these pathogens Therefore, chlorine dioxide has already replaced chlorine or ozone in industries such as medical and health care, food processing, environmental protection, industrial water, animal husbandry, and sewage treatment, and has been widely used for disinfection, sterilization, and deodorization. [0003] And check, because chlorine dioxide gas is a strong oxidizing agent, so it is difficult to preserve, even if chlorine dioxide gas is ...

AI Technical Summary

Problems solved by technology

[0004] Whether chlorine dioxide is prepared by chemical acid method or electrolysis method, although it has a certain degree of convenience; however, it must first mix reagents or make chlorite (ClO 2 - ) solution activation, or must produce chlorine dioxide gas by electrolysis of saturated salt water, but the operation is cumbersome and inconvenient, and the lack of chlorine dioxide gas cannot be obtained quickly; especially, whether it is produced by chemical acid method or electrolysis method Chlorine dioxide gas, which will continue to be released into the air, and as time goes on, the concentration of chlorine dioxide will continue to decrease, and then there is a lack of long-term storage for subsequent disinfection and sterilization operations Therefore, for how to obtain chlorine dioxide fast to carry out disinfection and sterilization, and how to preserve chlorine dioxide gas for a long time, it is actually a problem to be solved at present
