Abstract

The invention relates to a preparation method for nano magnesium peroxide. Using magnesium oxide, ammonium chloride, and oxydol with mass percentage of 30% according to the mass ratio of 1:(1.5-2.5):(30-40); dissolving the magnesium oxide into deionized water and grinding into magnesium oxide size mixture with the mass percentage of 3-4%; dissolving the ammonium chloride into the oxydol, and stirring and slowly adding into the ground magnesium oxide size mixture; keeping the reaction under the continuous stirring at 500 r / min for 3-4 h to obtain white precipitate mixed solution; filtering the white precipitate mixed solution to obtain a wet filter cake; performing freezing vacuum drying at -80 DEG C to obtain a target product of nano magnesium peroxide powder with particle size of 20 nm, good dispersity, and purity higher than 50%. The method is simple to operate and is suitable for large-scaled industrialized production.

Description

technical field

[0001] The invention relates to a preparation method of nano-magnesium peroxide, which belongs to the technical field of chemical synthesis methods. Background technique

[0002] Magnesium peroxide, molecular formula MgO 2 , is a solid inorganic peroxide. Appearance is white powder, odorless and tasteless, insoluble in water, soluble in dilute acid. It is relatively stable at room temperature. When heated or in contact with humid air, it will release oxygen slowly and steadily. When dissolved in acid, it will produce hydrogen peroxide. Magnesium peroxide is non-toxic and non-polluting to the environment, so it is widely used in many fields such as medicine, textile industry, mining industry, and agriculture.

[0003] In the field of environmental protection, magnesium peroxide can be used as an oxygen-releasing compound for in-situ chemical oxidation, and as a raw material for soil, sediment, surface water and groundwater pollution remediation. The relati...
