Background technology
Human use's chemosterilant carries out sterilizing since 19 beginnings of the century.First generation chemical disinfection in 1820
After the advent of agent bleaching powder, people are mainly used in the treatment of drinking water disinfection and contaminated wound, and are achieved and imitated well
Fruit opens first milestone of chemical sterilization disinfection.Hereafter, people are found that second generation disinfectant ethylene oxide in succession,
Third generation disinfectant glutaraldehyde.As the chlorine dioxide of forth generation disinfection sanitizer, the sodium hypochlorite industry before and after 1940
After metaplasia production, people just start large-scale use.The Big Fall In Niagara in the U.S. in 1940 is taken the lead in being handled using it and be drunk
Water obtains good result, is generalized to the whole world rapidly later.People are when discovery carries out disinfection to drinking water with chlorine successively, water
In organic matter can with chlorine occur substitution reaction, generate organochlorine compound, organochlorine can be accumulated in human body generate it is chronic
Progressive poisoning, can also induce carninomatosis, and environmental protection alliance of the world will completely forbid the disinfection that drinking water is used for using chlorine, it is proposed that adopt
The disinfection of drinking water is carried out with universal, the high effect disinfectants chlorine dioxide with strong oxidizing property.Chlorine dioxide is by the United Nations
Health organization（WHO）It is classified as I grade of disinfectant of A.China starts from the eighties using Chloride Dioxide Disinfection Technology.1987, Guangdong
Province health supervision department ratifies it and can be used for food sterilization, fresh-keeping and food apparatus, equipment disinfection.Nineteen ninety Shanghai sanitation pipe
Reason department ratifies it and can be used for water process, food processing and aquaculture, deodorization etc..The Ministry of Public Health of China is also before 2000
It clearly proposes, gradually substitutes the disinfection that chlorine carries out drinking water with chlorine dioxide.Chlorine dioxide is generally acknowledged in the world a new generation
Efficient, wide spectrum, the sterilization of safety, antistaling agent, be the optimal substitute of chlorinated product, obtained extensively in World Developed Countries
Application.The related organization of the developed countries such as the U.S., West Europe, Canada, Japan such as Environmental Protection Agency USA, food and medicine management
Office, United States Department of Agriculture ratify and recommend chlorine dioxide disappearing for food, food processing, pharmacy, hospital, public environment etc.
Malicious, mould proof and food anti-corrosive fresh-keeping etc..The World Health Organization（WHO）With world food tissue (FAO) also by chlorine dioxide
It is classified as A1 level security high effect disinfectants.In drinking water in order to control " three cause substance "（Carcinogenic, teratogenesis, mutagenesis）Generation, America and Europe hair
Chlorine dioxide, which is had been widely used, up to country substitutes the disinfection that chlorine carries out drinking water.2006 or so, China also began to attention two
Aoxidize the promotion and application of chlorine products.National Standard of the People's Republic of China's stability dioxy has been promulgated on June 1st, 2006
Change solutions of chlorine（GB/T20783-2006）, health ministry approved chlorine dioxide is disinfectant and new food additive.
Chlorine dioxide is a kind of wide spectrum, efficient bactericidal agent.External many results of study show chlorine dioxide extremely low
Concentration（0.1ppm）Under, you can kill the pathogenic bacteria such as many Escherichia coli, staphylococcus aureus.Even if in organic matter
Interference under, using a concentration of tens ppm when, can also kill bacterial propagule, hepatitis virus, bacteriophage and bacterium bud completely
All microorganisms such as spore.Chlorine dioxide is applied to by developed country nearly all needs sterilizing field.In China, dioxy
The application for changing chlorine is although at the early-stage, but it is believed that in the near future, chlorine dioxide is bound to become production and life
In essential articles for daily use, development prospect is infinitely wide.
Chlorine dioxide has extremely strong oxidability, should avoid at high concentrations（>500ppm）It uses.When low using concentration
When 500ppm, the influence to human body can be ignored, and when 100ppm or less will not generate human body any influence, including life
The influence of the biochemical aspect of reason.To skin also without any sensitization.In fact, the routine of chlorine dioxide will be much using concentration
Less than 500ppm, normally only in 50ppm-100ppm or so.But chlorine dioxide bactericide currently used in the market mainly with
ClO 2 solution or the powder constituent of dry marquis, cannot accomplish the effect of sustained release, and since concentration is not easy to quantify, make
It is possible to excess in, harmful effect is had to human body.
