|The hydrogen peroxide is widely used thanks to its very good properties. Indeed H2O2 is safe, effective, powerful and versatile oxidant. |
The table below lists the oxidation Potential scale, hydrogen peroxide is more powerful than chlorine or chlorine dioxide for instance. Furthermore through catalysis, hydrogen peroxide can be converted into hydroxyl radicals which is the second stronger oxidant after fluorine.
There are several advantages in using H2O2:
The main applications of H2O2 are numerous, such as the odor control, corrosion control, BOD/COD removal, organic oxidation, metal oxidation, toxicity oxidation and disinfection. Besides hydrogen peroxide can be combinated with different processes to improve the results: flocculation/precipitation, Air flotation, biotreatement, filtration, carbon adsorption, air scrubbers and incineration.
The most difficult pollutant to oxidize may require H2O2 to be activated with catalysts such as iron, copper, manganese or other transition metal compounds. The most common used solution catalyst is iron, which when is used with H2O2 is called Fenton's reaction.
