text: (It is easiest to use concentrated forms for this, but after adding to a bath or pool or fountain, the concentration will be very low, such as 1/10th of 1% or lower.)
text: The stoichiometry calls for 1.0 lb H2O2 per lb H2S, and it is not unusual for efficiencies to approach 100%, particularly when the concentrations of other oxidizable substances (e.g., thiosulfate) are low, and when the reaction is accelerated by catalysis.
text: In the environment, hydrogen peroxide can be found in very low concentrations.
text: In this initial proof-of-concept unit, the concentration of hydrogen peroxide produced is still low, but further engineering of the system should lead to being able to produce more concentrated output, Surendranath says.
text: Hydrogen peroxide is formed in plant and animal cells, but its concentration is very low because hydrogen peroxide is decomposed rapidly by the action of the enzymes catalase and peroxidase and because it is rapidly taken up to oxidize organic compounds.
text: The reaction can be carried out by Br 2 in the absence of H 2 O 2 in a two-phase system; also in this case, the stationary concentration of HBr is very low in the organic phase, because of the much higher solubility of HBr in the aqueous phase.
text: However, the risk can be easily managed if the flow is small and HCHO concentrations are low - i.e., for a 3,500 mg/L HCHO stream, the level of hydrogen that would be generated would be 117
text: The disproportionation reaction involving a molecule of superoxide radical (153) with a molecule of hydroperoxyl radical (154) is rapid and, although the concentration of (154) is low, this reaction predominates over the dismutation reaction involving two molecules of (153), which is relatively slow (Equation (3) (3). ).
text: In this initial proof-of-concept unit, the concentration of hydrogen peroxide produced is still low, but further engineering of the system should lead to being able to produce more concentrated output, Surendranath says.
