Luminol

Luminol is one of the oldest and most commonly used reagents, which can be oxidized by peroxides under alkaline conditions while emitting light. The oxidation-reduction reaction between luminol and peroxides requires a catalyst, which is generally a multivalent metal ion, peroxidase such as iron, spicy root peroxidase, etc. This method is commonly used to detect the content of peroxides, heavy metals, peroxidase, as well as the derived detection of free radicals, toxin analysis, and analysis methods based on peroxidase and glucose oxidase.
