Hydrogen Peroxide Detection

CAS Number: 7722-84-1
STEL: 2ppm
TWA: 1ppm

Properties

Hydrogen Peroxide (H2O2) is a clear, unscented and oily liquid that is water insoluble. It can be extracted with mercury oxide after dissolving α-ethyl anthraquinone in an industrial solvent and oxidising in a (redox reaction). In general, hydrogen peroxide is commercially available as a 30% solution.

It also interacts as a reducing agent and a powerful oxidiser. When metal catalysts in fine particle form (e.g. copper, silver or platinum) trigger decomposition, high concentrations of oxygen/steam are produced that can combust explosively.

Dangers

It is highly caustic to skin and mucous membranes, while a 30% solution can cause severe inflammation of eyes and skin upon contact. It is commonly known, that in work environments where Hydrogen Peroxide is in use, exposure to the vapour can have a bleaching effect on hair. If larger quantities are ingested, gastritis and acute toxic effects such as esophagitis, and chronic toxicity symptoms are likely.

Where is it found

Hence, Hydrogen Peroxide is used in 3% solutions not only as a disinfectant, or a bleaching agent for paper, pulp, and natural fibers, but, also as an oxidiser, steriliser, reducing agent, and even as liquid rocket fuel.
