Description
Technical field
The present invention relates to environmental protection and health care disinfection technology field, specifically be meant a kind of preparation method of chlorine-containing disinfecting water.
Technical background
Chlorine-containing disinfectant is the most widely used a kind of disinfectant, comprises polytype, like clorox, chlorine ammonia-T, sym-closene, sodium dichloro cyanurate etc.Because chlorine-containing disinfectant has cheapness, advantage such as efficient, is widely used in drinking water disinfection, environment disinfected, fields such as health care sterilization, be use in the world at present one type of disinfectant the most widely.
Chlorine-containing disinfectant mainly contains two kinds of formulations: solid dosage forms and liquid dosage form.Solid dosage forms most species, available chlorine content are generally in the 20-90% scope.Liquid dosage form is less, and main component is a clorox, available chlorine content 5-12%.
The sterilization of dissimilar chlorine-containing disinfectants is similar basically with sterilizing mechanisms, and these disinfectants dissolve or dilute the back and produce the hypochlorous acid molecule in water, generates active chlorine (also claiming available chlorine) and carries out disinfection.
At present, the greatest problem of chlorine-containing disinfectant existence is:
(1) chlorine-containing disinfectant is after dissolving or dilution, and available chlorine is unstable in the aqueous solution, and especially under neutrality and acid medium condition, the half life period generally has only tens hours.Therefore, chlorine-containing disinfectant can not long preservation after dissolving and dilution, is inconvenient to use.
(2) the hypochlorous acid molecule decomposes in water and discharges gas Cl
2, gas Cl
2Contaminated environment not only, but also can cause shed tears, cough, chafe and mucous membrane, severe patient causes poisoning, is choked to death and dies.When working concentration was big, the people was unsuitable on the scene.Therefore, chlorine-containing disinfectant generally should not be applied to disinfection of indoor air.
(3) chlorine-containing disinfectant is a kind of high effect disinfectants, and stronger excitant is arranged, and generally should not be applied to the sterilization of human body skin and mucous membrane.
For above-mentioned reasons, the application of chlorine-containing disinfectant is very limited.Though, developed some quite more stable chlorine-containing disinfection liquids in recent years, all be that hypochlorous sodium solution is main sterilization composition.Its stability is similar with traditional clorox, has both made under lucifuge, sealing condition, in 1 year about available chlorine decline 20-35%.But after being diluted to working concentration (is 100-1000mg/L like effective cl concn), available chlorine is unstable equally, and the half life period of available chlorine generally has only several days.In recent years, the report of complexing chlorhexidine-containing disinfectant is arranged also, but available chlorine stability or undesirable, deposited 78 days in the darkroom, its available chlorine percent of loss is 62-67%, and obvious gas Cl is in use arranged
2Taste.
Therefore, if can solve the stability problem of chlorine-containing disinfectant aqueous solution available chlorine, alleviate its excitant; With the range of application that further enlarges chlorine-containing disinfectant; Can chlorine-containing disinfectant be applied to fields such as disinfection of indoor air, skin degerming, market prospects are wide, and to the protection environment; Human body health has great importance, and social benefit is far-reaching.
Chinese invention patent CN101006782A discloses a kind of preparation method of stable high potential chlorine-containing disinfection liquid, and the complexing agent of employing is the alkyl amino sulfonic compound.The shortcoming of this method is: the disinfecting power of the thimerosal of being prepared is influenced greatly by the pH value of system, and the pH value of system increases after the several times dilution, and disinfecting power obviously descends; Stationary phase is generally less than 1 year; Alkyl amino sulfonic compound large usage quantity has stimulation to skin, influences its range of application.
Summary of the invention
The objective of the invention is provides a kind of preparation method of chlorine-containing disinfecting water in order to solve the above-mentioned deficiency that existing chlorine-containing disinfection liquid and chlorine-containing disinfectant exist.This method is used a kind of compound complex agent, a kind of chlorine-containing disinfectant, a kind of stabilizing agent and water by certain proportioning preparation.Not only the available chlorine retention period is long for the chlorine-containing disinfecting water of being prepared, and has stronger disinfecting power.
Compound complex agent according to the invention is the mixture of NPE ammonium sulfate and polyvinylpyrrolidone, and both weight ratios are: polyoxyethylene ether ammonium sulfate: polyvinylpyrrolidone is 4: 1-1: 2, preferred 2: 1-1: 1.Stabilizing agent according to the invention is a sulfamic acid amine; The not special restriction of said chlorine-containing disinfectant; Can be chlorine-containing disinfectants such as clorox, calcium hypochlorite, Efficacious Disinfeitant, sym-closene, sodium dichloro cyanurate, but preferred available chlorine content be higher, water-soluble better, the malicious lower sodium dichloro cyanurate of property.These three kinds of components unit are by weight counted: NPE ammonium sulfate+polyvinylpyrrolidone 30-40%, and chlorine-containing disinfectant (by available chlorine) 20-25%, sulfamic acid amine 30-40%.
The not special restriction of institute of the present invention water can be adopted distilled water, pure water or running water, preferred pure water.
The preparation method of a kind of chlorine-containing disinfecting water according to the invention; Its compound method is with after polyvinylpyrrolidone mixes by a certain percentage with NPE ammonium sulfate; In 45-50 ℃ water, dissolve; Add chlorine-containing disinfectant then, add stabilizing agent again, be diluted with water to needed concentration at last.These four kinds of components unit are by weight counted: complexing agent 0.05-2.0%; Chlorine-containing disinfectant (in available chlorine content) 0.02-0.6%; Stabilizing agent 0.05-2.0%; Water 95-99%.The effective chlorine density of the chlorine-containing disinfecting water of preparation is 0.02%-0.6% (but not receiving this concentration limit).
Principle of the present invention is: the good dispersion that NPE ammonium sulfate and polyvinylpyrrolidone all have and water-soluble; They dissolve the back in water can form the indefinite form complex compound with the hypochlorous acid molecule that the chlorine-containing disinfectant hydrolysis forms, and both mix the back and have the obvious synergistic effect for this complexing; The adding of sulfamic acid amine can be stablized this indefinite form complex compound more, makes that available chlorine is highly stable in the aqueous solution; In use, this chloro-complex that contains discharges free hypochlorous acid molecule gradually, thereby carries out disinfection and sterilization.
