Hydrogen peroxide chemical formula for H2O2, is an inorganic compound, pure hydrogen peroxide is light blue viscous liquid, can be any proportion of water miscible, is a strong oxidant, aqueous solution commonly known as hydrogen peroxide, is a colorless transparent liquid. Its aqueous solution is suitable for medical wound disinfection and environmental disinfection and food disinfection. Under normal circumstances, it will slowly decompose into water and oxygen, but the decomposition rate is extremely slow. The way to speed up the reaction rate is to add catalyst such as manganese dioxide or irradiate with short-wave rays.Hydrogen peroxide has oxidation and reduction under different conditions. Used for photographic stain remover; blue thinning of color positive film; ultra-proportional thinning of film, etc. Very easy to decompose, not easy to long-term storage.According to the chemical properties and physical properties of hydrogen peroxide, the use can also be divided into three main types.

The first one in daily disinfection ismedical hydrogen peroxideMedical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic cocci, pathogenic yeast, generally used for surface disinfection. Hydrogen peroxide has oxidation effect, but the concentration of medical hydrogen peroxide is equal to or lower than 3%. When wiped to the wound surface, there will be burning sensation, the surface will be oxidized to white and bubbles will emerge. Just wash it with clear water and restore the original skin color in 3-5 minutes.

The second chemical industry is used as a raw material for the production of sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide, etc., and an oxidant for tartaric acid, vitamins, etc. Third KindThe printing and dyeing industry is used as a bleaching agent for cotton fabrics, and the hair color after vat dye dyeing.goodUsed to remove iron and other heavy metals in the production of metal salts or other compounds. It is also used in electroplating solution to remove inorganic impurities and improve the quality of plated parts. Also used for wool, raw silk, ivory, pulp, fat and other bleaching. High concentrations of hydrogen peroxide can be used as rocket-powered combustion aidsWait。

In the face of today'sEpidemic situationWe don't know when it will end, it will be a long battle, we must make all preparations, daily disinfection work, safety protection is inevitable, in the first hospital should do more solid protection, regular disinfection work is certainly inevitable, so since the disinfection effect of hydrogen peroxide is so large, is the higher the concentration, the better the effect? The answer is no,2017Year10Month27On the same day, the World Health Organization's International Agency for Research on Cancer published a preliminary list of carcinogens for reference, hydrogen peroxide in3In the list of carcinogens. And high concentrations of hydrogen peroxide are strongly corrosive. Inhalation of the product vapor or mist is strongly irritating to the respiratory tract. Direct eye contact with liquid can cause irreversible damage and even blindness. Oral intoxication occursAbdominal pain, chest pain, dyspnea, vomiting, temporary motor and sensory disturbances, increased body temperatureWait. Individual cases appearVisual impairment, epileptiform spasms, paresis. This proves that in fact, in addition to disinfection and other effects, hydrogen peroxide may also threaten the safety of people's lives, which means that the hospital is using hydrogen peroxide.Disinfection and sterilizationThe concentration of hydrogen peroxide must also be strictly controlled, otherwise it may cause accidents, so how can the concentration of hydrogen peroxide be detected, so that the sterilization effect can be judged, and the concentration can be controlled within a safe range.

  There are also many sensors on the market that can detect hydrogen peroxide. Among many products, we may have difficulty choosing for a while, and it is difficult to choose products that can satisfy ourselves for a while. After all, it involves the safety of human life and property.Alphasenseis a company focused on the production of gas sensors, and a masterThe most authoritativeof Gas Sensor Technology, Shenzhen Agent of UKAlphasensehydrogen peroxide sensorH2O2-B1hasHigh sensitivity, linearity, resolutionIt can be used for testing in safety fields such as medical killing.
