Magnesium peroxide, decomposition

Figure 10.23 Effect of Fe(m) ion concentration on rate of hydrogen peroxide decomposition in absence of substrate [237]. Initial concentration 2.9 g/l H202, Sodium silicate 5 g/l, Magnesium sulphate 0.2 g/l, 95 °C, pH 12...

Magnesium peroxide can also be utilized in the remediation of soils contaminated with hydrocarbons. In this process, slurry of the peroxide is injected into a small bore hole that penetrates into the zone of contamination. The slow decomposition of the compound releases oxygen into the surrounding contaminated soil, which encourages the growth of aerobic hydrocarbon metabolizing bacteria (Konenigsberg, 1997). 

MAGNESIUM PEROXIDE (14452-57-4) Flammable solid. Dust or powder forms explosive mixture with air. Contact with moisture causes the release of oxygen and heat may ignite spontaneously. A powerful oxidizer. Violent reaction or decomposition with reducing agents, catalysts, ethers, thiocyanates. Dangerous fire risk with acidic and combustible materials. May be shock- and/or heat-sensitive explosive.
