The function of hydrogen peroxide is to kill a variety of bacteria and other microorganisms and play the role of disinfection. Hydrogen peroxide is a strong oxidant. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection.
In general, it will 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 or irradiate with short wave rays.
Use of hydrogen peroxide:
There are three kinds of hydrogen peroxide water for medical, military and industrial use. Medical hydrogen peroxide is used for daily disinfection. Medical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic cocci and pathogenic yeasts. It is generally used for object surface disinfection.
Hydrogen peroxide has oxidation effect, but the concentration of medical hydrogen peroxide is equal to or lower than 3%. When it is wiped on the traumatic surface, it will feel burning, the surface will be oxidized to white and bubble. Just wash it with clean water and restore the original skin color 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, etc., and as oxidants for tartaric acid, vitamins, etc. The pharmaceutical industry is used as a bactericide and disinfectant, as well as an oxidant for the production of thiram insecticide and 40L antibacterial agent. The printing and dyeing industry is used as a bleaching agent for cotton fabrics and a chromogenic agent after dyeing with vat dyes.
It is used 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. It is also used for bleaching wool, raw silk, ivory, pulp, fat, etc. High concentration hydrogen peroxide can be used as rocket power fuel.
