Hydrogen peroxide is used for sanitizing in food processing, medical field, household cleaning and so on.
In food processing, hydrogen peroxide is widely used for disinfecting the surface of food, especially for eliminating garbage and chemical residues on the surface of fruits and vegetables, as well as for preventing the infestation of germs and fungi in food, in order to guarantee the safety and hygiene of food.
In medical work, hydrogen peroxide is widely used in the disinfection of blood, plasma, medicines, medical equipment, disinfection of equipment, as well as surgery and other aspects of the disinfection work. Hydrogen peroxide has the ability to kill a variety of bacteria, especially for some common hospital infections pathogens have a strong bactericidal effect, is a very safe and efficient disinfectant.
In terms of home cleaning, hydrogen peroxide is also often used for daily cleaning and disinfection of the home, which can effectively eliminate bacteria and pathogens in the environment and safeguard the health of your family. For example, using hydrogen peroxide to clean common areas such as kitchen countertops and restrooms can not only sterilize, but also effectively eliminate odors, making the entire home environment cleaner and more hygienic.
Properties of hydrogen peroxide:
Hydrogen peroxide shows weak acidity, is a binary weak acid, there is an ionization balance in its solution, so it is acidic. Hydrogen peroxide, also known as hydrogen peroxide, hydrogen dioxide, is a peroxide disinfectant, is the product of certain reducing substances and oxidation in nature, rare, only trace amounts exist in some plant sap and rain and snow.
Physical properties: aqueous solution is colorless transparent liquid, soluble in water, alcohol, ether, insoluble in benzene, petroleum ether. As long as the storage conditions are good, no impurity pollution, pure hydrogen peroxide is relatively stable, can be stored for a long time and rarely decomposed, but heat to 153 ℃ or higher temperatures will be violent explosive decomposition.
Chemical properties: hydrogen peroxide in alkaline media decomposition rate is much faster than in acidic media, the important factors affecting its stability are impurities (many heavy metal ions, such as: Fe2 +, Mn2 +), pH, temperature, light, and storage containers, such as the roughness of the inner surface. High concentrations of hydrogen peroxide can make many organic solvents combustion, and manganese dioxide and mutual reaction can be explosive.
