Piranha solution (original) (raw)
Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2), used to clean organic residues off substrates. Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most surfaces (by adding –OH groups), making them highly hydrophilic (water-compatible). This means the solution can also easily dissolve fabric and skin, potentially causing severe damage and chemical burns in case of inadvertent contact.

| dbo:abstract | Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2), used to clean organic residues off substrates. Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most surfaces (by adding –OH groups), making them highly hydrophilic (water-compatible). This means the solution can also easily dissolve fabric and skin, potentially causing severe damage and chemical burns in case of inadvertent contact. (en) Le mélange piranha est un mélange de concentration variable d'acide sulfurique H2SO4 et de peroxyde d'hydrogène H2O2. Celui-ci sert à produire l'« acide de Caro » ou acide peroxymonosulfurique H2SO5 selon la réaction suivante : H2SO4 + H2O2 → H2SO5 + H2O. Le mélange piranha est une solution acide très oxydante et corrosive. Il sert à éliminer les résidus organiques les plus récalcitrants sur divers substrats, notamment sur le silicium des galettes de semi-conducteurs. C'est le seul système aqueux connu capable de dissoudre le carbone élémentaire (graphite et diamant) en l'oxydant irréversiblement en CO2.

De oplossing wordt onder andere gebruikt om goudoppervlakken te reinigen, voordat men er biologische preparaten op deponeert, zoals DNA.

Ponieważ mieszanina ta jest silnym środkiem utleniającym, usuwa większość materii organicznej i prowadzi do hydroksylacji większości powierzchni (dodaje grupy OH), czyniąc je wysoce hydrofilowymi.
