Magnesium peroxide|CAS1335-26-8

Magnesium peroxide MgO2 is a long-acting, temperature-friendly and harmless oxygenating agent. It has very important applications in agriculture, river sewage treatment, oxidation bottom mud, bleaching and other industries. The action mechanism of magnesium peroxide is mainly through the reaction with water, slowly releasing oxygen under certain environmental conditions, so as to achieve sterilization, bleaching and disinfection. Magnesium peroxide MgO2(1335-26-8) is a widely used and versatile inorganic peroxide with a longer dilution period, a smaller PH conversion range and a higher release per unit area, making magnesium peroxide ideal for use in soil bioimprovement and groundwater treatment. In agricultural cultivation, magnesium peroxide is used for oxygen supply of plant roots, coating of rice seeds, oxygen fertilizer and bio-compound fertilizer. In aquaculture, it can be used as an oxygen releasing agent to increase dissolved oxygen in water, adjust the PH value of water, improve water quality, and eliminate pathogenic bacteria. In addition, magnesium peroxide is also used in tooth bleaching agents, hair dyes and so on.

Product introduction

Magnesium peroxide MgO2 provides a stable release of oxygen and is suitable for use in agriculture or environmental related industries, such as reducing the content of groundwater pollutants, but because it introduces its own chemicals, it is only used to restore groundwater that has already been contaminated. It is also used to restore contaminated soil and improve plant growth and metabolism. The addition of MgO2 to compost can promote microbial activity while reducing the resulting odor produced by compost. In some cases, magnesium peroxide can also inhibit the growth of sulfate-reducing bacteria, possibly because slowly decomposing peroxy ions replace sulfate ions in the electron transport chain of the reaction.

Production method

Light magnesium oxide process Light magnesium oxide is reacted with hydrogen peroxide slurry and dried to obtain magnesium peroxide. MgO+H2O2=MgO2+H2O

Soluble magnesium salt method is used to make milk of soluble magnesium salt, react with hydrogen peroxide, filter and concentrate to produce magnesium peroxide.

Packing: 25Kg plastic woven bag with thin polyethylene lining

Storage: Store in a dry, clean and well-ventilated warehouse. Keep away from fire, heat sources and direct sunlight, magnesium peroxide can not be mixed with flammable or combustible materials, reducing agents, etc. Pay attention to moisture and rain.

Magnesium peroxide MgO2 is a white or slightly yellow powder, odorless, tasteless, insoluble in water, easily soluble in acid. Magnesium peroxide MgO2 is a very stable peroxide that is not easy to decompose at room temperature, begins to decompose at 350 ° C, and can slowly release oxygen in humid air or water for a long time. With strong bleaching, sterilization, disinfection and other effects, no harm to the environment.
