There is more than one recipe for piranha solution. The basic protocol combines concentrated sulfuric acid and aqueous hydrogen peroxide. Use 30% hydrogen peroxide in water. A higher concentration, such as 50% peroxide, greatly increases the temperature of the reaction and the risk of explosion. The 3:1 and 5:1 ratios of concentrated sulfuric acid ...
Research indicates chilling the peroxide solution before adding it to the sulfuric acid increases the potency of the piranha solution.Prepare the minimum volume needed for the application.Piranha solution rapidly decomposes, so make the solution fresh before use.Do not seal the container!Piranha solution works by three processes: 1. Sulfuric acid and hydrogen peroxide react to form Caro’s acid, which is also known as peroxymonosulfuric acid or persulfuric acid (H2SO5): H2SO4 + H2O2 → H2SO5 (Caro’s acid) + H2O The dehydrationrapidly carbonizes organics, particularly carbohydrates. Caro’s acid also attacks elemental carbon, including...
Piranha solution should be prepared fresh and not stored. Sulfuric acid should be stored in an acid cabinet, while hydrogen peroxide solutions decompose more slowly stored in a refrigerator. Neutralize piranha solution immediately following use. There are two methods:
To Clean Sintered Glass– Piranha solution is preferred over a strong base to clean sintered glass or fritted glass because it doesn’t damage pores in the glass. Soak the glassware overnight in pira...To Clean Glassware– Piranha solution can remove contamination on glassware. It’s important there is not excessive organic contamination. Soak the glassware overnight, then thoroughly rinse it.To Make Glass Hydrophilic– Apply as a surface treatment to glass to make it hydrophilic. Piranha solution increases the number of silanol groups on the glass surface by hydroxylating the silicon di...To Remove Surface Residue– Only use piranha solution to remove residue, not a substantial layer.Jones, C.

Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers . [1]
Dec 29, 2021 · Piranha solution is a dangerous and useful substance used throughout academia and industry. However, there is little peer-reviewed work on its safe use, and institutional protocols are limited in their applicability beyond their institute of origin.
