Further knowledge into effects of cleaning mesoporous silica SBA-15. Reactivity. Bonita Springs, FL34135 Piranha solutions are extremely energetic and may result in explosion or injury resulting from chemical and thermal burns if not handled with extreme caution. In addition, the vapors emitted from boiling piranha can cause severe burns to the respiratory tract if inhaled. What chemicals are good to dissolve a body? : r/chemistry - Reddit This study provides a facile approach to prepare organosilicas for potential higher loading capacities. the World's Strongest Superacid Can you dissolve a body in hydrogen The OSHA PEL and ACGIH TLV for hydrogen peroxide are both 1 ppm as an 8-hour time- For quantities over 100ml, the spent, reacted piranha solution should be collected as waste. A clean, recycled sulfuric acid bottle is a good option. Initially, add only a small amount of the solution to waste container to ensure that there are no residual materials in the container that may cause an adverse reaction. If no reaction is observed, continue to pour slowly. The bottle should be explicitly labeled as containing waste piranha solution. WebPiranha solution is only to be collected for disposal after it has fully reacted, cooled and the gases of reaction have had adequate time to dissipate. The term piranha refers to a hot solution of sulfuric acid and hydrogen peroxide (also known as SPM), which can hydroxylate many surfaces (adding OH groups) as well as strip photoresist and other organic materials by oxidizing them and remove metals by forming complexes that remain in the solution. 4925 SW 74th Ct A Piranha solution composed of hydrogen peroxide and sulfuric acid is even better and will dissolve almost anything. The hydrogen peroxide concentration should be kept under 30% and should NEVER exceed 50%. Depending on the preparation procedure (see below), piranha solutions can contain up to 5% peroxymonosulfuric acid. I know this is an old question, but it gets viewed a lot so I thought I would update with the fact that this experiment was actually done on the fi
