What are the uses of hydrogen peroxide?
Hydrogen peroxide can be used for medical use, military use and industrial use. It is used for daily disinfection. It can kill intestinal pathogenic bacteria, pyogenic cocci and pathogenic yeast. It is generally used for disinfection of object surface. Hydrogen peroxide has oxidation effect, but the concentration of medical hydrogen peroxide is equal to or less than 3%. When it is wiped to the wound surface, there will be burning feeling, the surface will be oxidized to white and bubbles, and then it can be cleaned with water, and the original skin color will be restored in 3-5 minutes.
The chemical industry is used as raw materials for the production of sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide, tartaric acid, vitamin, etc. The pharmaceutical industry is used as a bactericide, disinfectant, and oxidant for the production of thiram and 40L antibacterial agents. Dyeing and printing industry is used as bleaching agent of cotton fabric and hair color after vat dyeing. Used to remove iron and other heavy metals when producing metal salts or other compounds. It is also used in electroplating solution to remove inorganic impurities and improve the quality of plating parts. It is also used for bleaching wool, raw silk, ivory, pulp, fat, etc. High concentration hydrogen peroxide can be used as rocket power combustion supporting agent.
Civil use: to deal with the peculiar smell of kitchen sewage, to buy hydrogen peroxide in drugstore, add water and washing powder and pour it into the sewer to decontaminate, disinfect and sterilize;
3% hydrogen peroxide (medical grade) can be used for wound disinfection;
Introduction to hydrogen peroxide: hydrogen peroxide, chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid, which can be mixed with water in any proportion. It is a strong oxidant. The aqueous solution, commonly known as hydrogen peroxide, is a colorless and transparent liquid. Its aqueous solution is suitable for disinfection of medical wound, environment and food. In general, it will slowly decompose into water and oxygen, but the decomposition speed is extremely slow. The way to speed up the reaction speed is to add catalyst - manganese dioxide, etc. or use short wave radiation.
In different conditions, it has oxidation and reduction. It is used for photo decontamination agent, blue thinning of color positive film, over scale thinning of film, etc. It's easy to decompose, not to last.
