Hydrogen peroxide is an inorganic compound with the chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid that can be miscible with water in any proportion. It is a strong oxidant. Its aqueous solution is commonly known as hydrogen peroxide and is a colorless and transparent liquid. Its aqueous solution is suitable for medical wound disinfection, 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 is to add a catalyst (manganese dioxide, etc. or irradiate with shortwave rays)
Hydrogen peroxide is usually formulated as an aqueous hydrogen peroxide solution for use.
Hydrogen peroxide is used for medical, military and industrial purposes. The daily disinfection is medical hydrogen peroxide. Medical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic cocci, and pathogenic yeasts. It is generally used for surface disinfection. Hydrogen peroxide has an oxidizing effect, but the concentration of medical hydrogen peroxide is equal to or lower than 3%. When wiped on the wound surface, there will be a burning sensation, the surface will be oxidized to white and air bubbles, just wash it with water, and it will take 3-5 minutes to Restore the original complexion.
In the chemical industry, it is used as raw materials for the production of sodium perborate, sodium percarbonate, peroxyacetic acid, sodium chlorite, thiourea peroxide, etc., as well as oxidizing agents for tartaric acid and vitamins. In the pharmaceutical industry, it is used as a fungicide, disinfectant, and oxidant for the production of thiram insecticide and 40l antibacterial agent. In the printing and dyeing industry, it is used as a bleaching agent for cotton fabrics to reduce the color after dyeing with dyes. Used to remove iron and other heavy metals in the production of metal salts or other compounds. It is also used in electroplating solutions to remove inorganic impurities and improve the quality of plated parts. It is also used for bleaching wool, raw silk, ivory, pulp, fat, etc. The high concentration of hydrogen peroxide can be used as rocket-powered combustion aid.
Civil use: To deal with the peculiar smell of the kitchen sewer, buy hydrogen peroxide, add water and washing powder in the pharmacy, and pour it into the sewer to decontaminate, disinfect and sterilize;
3% hydrogen peroxide (medical grade) can be used for wound disinfection;
