Magnesium peroxide has the molecular formula MgO2, CAS: 1335-26-8. MgO2 is characterized by its high decomposition temperature, high oxygen content, susceptibility to acidity, and stability at room temperature. It appears as a white to slightly yellow powder and can be used as a bleaching agent, disinfectant, and bactericide. Magnesium peroxide slowly releases oxygen when it comes into contact with water; therefore, in aquaculture, adding an appropriate amount of magnesium peroxide can increase the dissolved oxygen content in the water, improving the living environment for aquatic organisms such as fish, shrimp, crabs, and sea cucumbers.

III. Production Process

Magnesium peroxide is produced by reacting magnesium oxide with hydrogen peroxide slurry and then drying. The reaction formula is MgO + H₂O₂= MgO₂+ H₂O

IV. Mechanism of Action

Magnesium peroxide (MgO2) has strong oxidizing properties; it can donate oxygen atoms to participate in redox reactions. In some organic synthesis reactions, magnesium peroxide can oxidize certain organic compounds into corresponding oxides or products such as aldehydes and ketones. It can destroy the molecular structure of organic pigments, thus achieving a bleaching effect. The oxygen released by MgO₂and its oxidizing properties help inhibit and kill bacteria, viruses, and other microorganisms. Magnesium peroxide decomposes organic pollutants through oxidation, and the released oxygen can promote the growth and metabolism of aerobic microorganisms, accelerating the wastewater purification process.

V. Packaging

25 kg/bag, woven bag or kraft paper packaging.

Magnesium peroxide decomposes when it comes into contact with water, organic acids, metal oxides, etc. During storage and use, care should be taken to store it separately from these substances. The main products of thermal decomposition include MgO and oxygen.
