Abstract

The invention relates to a javelle water and a preparation method thereof. The stable activation-state javelle water comprises the following components (wt percent): 4-7 sodium hypochlorite, 0.5-1sodium chlorate, 0.25-1.5 sodium chloride, 1-3 dodecyl dimethyl tertiary amine, 0.1-0.5 metal ion complexing agent, 0.1-0.5 organic phosphonic acid, 0.5-1.5 phosphonic acid, and water of rest percent. The preparation method comprises the following steps: according to the content and components, adding sodium chlorate and sodium chloride in the water and then stirring; adding the metal ion complexing agent and stirring the solution; adding the sodium chlorate and stirring the solution; adding the organic phosphonic acid and stirring solution; adding the dodecyl dimethyl tertiary amine and stirring solution; adding the phosphonic acid and stirring; and uniformly stirring the solution so as to obtain the javelle water. The javelle water provided by the invention has the advantages of stable quality, good sterilizing effect and convenience in use.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a sodium hypochlorite disinfectant and a preparation method thereof. Background technique [0002] Sodium hypochlorite is a highly efficient, broad-spectrum, safe and powerful fungicide. It has a good affinity with water and can be miscible with water in any ratio. It has no safety hazards such as liquid chlorine and chlorine dioxide, and its disinfection effect is recognized as equivalent to chlorine gas, so it is widely used in tap water, industry, etc. Disinfection of circulating water, swimming pool water, hospital sewage and other water bodies, as well as soaking and wiping disinfection of items contaminated by bacteria and viruses. The bactericidal principle of sodium hypochlorite is mainly to form hypochlorous acid through hydrolysis, which is further decomposed to form nascent oxygen. The strong oxidizing property of nascent oxygen denatures the proteins of bacteria and viruses, thereb...
