WebbContent may be subject to copyright. Luminol's mechanism of reaction (Step 2). In this second stage, the endoperoxide (III) after losing molecular nitrogen is in its excited state, … To exhibit its luminescence, the luminol must be activated with an oxidant. Usually, a solution containing hydrogen peroxide (H2O2) and hydroxide ions in water is the activator. In the presence of a catalyst such as an iron or periodate compound, the hydrogen peroxide decomposes to form oxygen and water: 2 H2O2 → O2 + 2 H2O H2O2 + KIO4 → KIO3 + O2 + H2O
