Hydrogen Peroxide

Hydrogen peroxide is an inorganic compound with the chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid that can be mixed with water in any proportion. It is a strong oxidant, and the aqueous solution is commonly known as hydrogen peroxide, which is a colorless and transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection, and food disinfection. In general, it will slowly decompose into water and oxygen, but the decomposition rate is extremely slow. The way to accelerate its reaction rate is to add catalysts such as manganese dioxide or irradiate it with shortwave radiation.

APPLICATION

Hydrogen peroxide also plays an important role in the food processing industry. It can be used for bleaching and disinfecting food contact surfaces, as well as as as a disinfectant for food packaging materials. In addition, hydrogen peroxide can also be used for certain chemical reactions in food processing, such as bleaching flour and vegetables.

In the textile industry, hydrogen peroxide is often used in bleaching and dyeing processes. It can remove natural pigments from the fabric to achieve a uniform white color, while also helping to improve the dyeing effect.

Hydrogen peroxide is mainly used for bleaching pulp in the papermaking industry. It can effectively remove lignin and other colored substances from pulp, resulting in higher whiteness and brightness of the paper.
