Abstract
The present invention provides an environmental-protection disinfectant composition which is very stable in a neutral water medium and an acidic water solution and has the advantages of no obvious stimulation, safety, high efficiency and no secondary pollution, and application of the disinfectant composition. The composition is composed of SF initial powder or sodium periodate, weak acid and pure water. The composition can be applied to environment disinfection, and can be widely suitable for sterilizing and disinfecting in public places, such as dining rooms, markets, hospitals, school laboratories, families, etc. and specific industries of pharmacy, environmental protection, etc. The composition is especially suitable for sterilizing and disinfecting the pathogenic bacteria of atypical pneumonia.
Description
Technical field
The present invention relates to a kind of iodates composition and the application in environment disinfected thereof.
Background technology
Disinfectant can be divided into bactericidal agent, high effect disinfectants, middle effect disinfectants, low effect disinfectants.Bactericidal agent: can kill all microorganisms and make it reach the preparation that sterilization requires.Comprise formaldehyde, glutaraldehyde, oxirane, Peracetic acid, hydrogen peroxide, chlorine dioxide etc.High effect disinfectants: can kill all bacterial propagules (comprising mycobacterium), virus, fungi and spore thereof etc., bacterial spore is also had certain killing action, reach the preparation of high level disinfection requirement.Comprise chlorine-containing disinfectant, ozone, methyl hydantoin compounds, double-chain quaternary ammonium salt etc.Middle effect disinfectants: only can kill microorganisms such as mycobacterium, fungi, virus and bacterial propagule, reach the preparation that sterilization requires.Comprise and contain iodine disinfectant, alcohol disinfectant, phenols disinfectant etc.Low effect disinfectants: but refer to only kill vegetative forms of bacteria and lipophilic virus, reach the preparation of disinfectant requirement.Comprise quaternary ammonium disinfectant, Chlorhexidine two guanidine class disinfectants such as (hibitane) such as benzalkonium bromide, metal ion class disinfectant and Chinese herbal disinfectants such as mercury, silver, copper.
Comprise than the common chemical disinfectant now: the peroxide disinfectant: because they have strong oxidability, various microorganisms are very responsive to it, can be with all microorganism killings.This class disinfectant comprises hydrogen peroxide (30% to 90% does not wait), Peracetic acid (18% to 20%), chlorine dioxide and ozone etc.They use inconvenience, and because of its oxidability is strong, can stimulate, damage skin and mucosa, corrosives during high concentration because unstable chemcial property needs matching while using.Wherein Peracetic acid is usually used in being can be used for air sterillization by viral pollution article or skin degerming in unmanned environment.Chlorine dioxide can be used for the article surface sterilization.Ozone also is a kind of strong oxidizer, bactericidal action is more obvious when water-soluble, be usually used in the sterilization of water, adding ozone amount during drinking water disinfection is 0.5 to 1.5 milligram every liter, surplus ozone amount is kept for 0.1 to 0.5 milligram every liter and can be reached the sterilization requirement in 10 minutes in the water, when water quality is relatively poor, should strengthen the ozone addition.Widely used in the market Peracetic acid class disinfectant ubiquity has the burn into bleaching, application on human skin, respiratory mucosa is had strong impulse, volatile, unstable article, and concentration descends soon in the storage, uses shortcomings such as inconvenience.
Chlorine-containing disinfectant: refer to that water-soluble generation has the hypochlorous disinfectant of microbiocidal activity, its microbicidel active ingredient is often represented with available chlorine.The hypochlorous acid molecular weight is little, easily is diffused into bacterium surface, and permeates cell membranes enters in the thalline, makes the mycoprotein oxidation cause bacterium death.Chlorine-containing disinfectant can be killed various microorganisms, comprises bacterial propagule, virus, fungi, tubercle bacillus and the strongest bacterial spore of drag.This class disinfectant comprises: inorganic chloride, as clorox (10% to 20%), bleaching powder (25%), bleaching powder (calcium hypochlorite is main, 80% to 85%), Efficacious Disinfeitant (3% to 5%); Organochlorine compound, as sodium dichloro cyanurate (60% to 64%), sym-closene (87% to 90%), oronain T inorganic chlorine character instabilities such as (24%), be subject to light, heat and moist influence, lose its active ingredient, organochlorine is then relatively stable, but all unstable after water-soluble.Their function of killing microorganism obviously is subjected to the influence of working concentration, action time.When organic matter (as blood, saliva and excreta) when existing Disinfection Effect can obviously descend.This type of disinfectant is usually used in sterilizations such as environment, article surface, tableware, drinking water, sewage, excreta, rubbish.CN1293540A discloses a kind of Weak acidic disinfectant, under solutions of weak acidity, water-soluble after, produce stable biocidal efficacies higher hypochlorous acid or chlorous acid, the concentration of available chlorine can be reduced between the 10-500ppm in the use.The high concentration chlorine-containing disinfectant has the obvious stimulation effect to human respiratory mucous membrane and skin, and article are had corrosion and discoloration, but a large amount of also contaminated environment of using.
Contain iodine disinfectant: comprise the tincture of iodine and Iodophor, their halogenation microproteins of relying make its death.But kill vegetative forms of bacteria, fungi and part virus.Can be used for skin, mucous membrane sterilization, hospital is usually used in the surgical hand sterilization.The working concentration of the general tincture of iodine is 2%, and the Iodophor working concentration is 0.3% to 0.5%.Iodophor disinfectant is the product that iodine combines with polyethylene pyrrole junket alkane ketone, and its seepage is in the liquid that is added with 10%KCl, and K and I affinity are strong, generate KI, the KI of high concentration has stronger spread effect to muscle, and the carrier that dissociates is a polyvinylpyrrolidone, can only be oral, can not inject vein.Iodophor is disinfectant for external use in addition, and is impure, and the carrier polyvinylpyrrolidone is a nature of soap material, enter liquid after, the foam that differs in size can appear in slight concussion.In addition, the above-mentioned iodine disinfectant that contains is generally colouredly, and iodine easily distils, and the term of validity is short, is generally limited to skin degerming.Disclosed chelated iodine liquid disinfectant among the CN 1114527A contains the iodine of 0.05～4 (percentage by weight), the polyethylene glycol of 1.0～40 (percentage by weights), the fatty alcohol-polyoxyethylene ether of 0.1～4 (percentage by weight), deionized water
Summary of the invention
In the face of " SARS " this precipitate national disaster, the problem to be solved in the present invention provides a kind of highly stable in neutral water medium and acidic aqueous solution, the new generation of environment protection disinfectant products and the application thereof of safe, efficient, the non-secondary pollution of no obvious irritation.
