How sensitive is luminol
NettetLuminol is a white-to-pale-yellow crystalline solid that is soluble in most polar organic solvents, but insoluble in water. Forensic investigators use luminol to detect trace amounts of blood at crime scenes, as it reacts with the iron in hemoglobin. Nettet28. feb. 2024 · The luminol is oxidized by the hyrogen peroxide in a basic solution to an excited state. The excited state of the luminol than changes back to the stable state with the emission of light. To exhibit its luminescence, the luminol must …
