<p>The spectrometric and colorimetric methods are used for determining hydrogen peroxide (H2O2) and are based on chemical reactions originated by the addition of chemical reactants that generate dyed compounds upon being reacted with the hydrogen peroxide, which are detected in a photometric manner at a predetermined light length. The disadvantages of these methods are their complexity that avoids the same to be automatically applied, requiring trained personnel for applying the same, also using chemical reactants that may cause problems in the clean room of a semiconductor company. These disadvantages are eliminated by a method that does not apply any chemical reactant, based on the thermal decomposition of the hydrogen peroxide and the measurement of the amount of oxygen produced by said decomposition, which would be proportional to the concentration of hydrogen peroxide.</p> |
