“…The function of hydrogen peroxide is to bring about the oxidation of the anion derived from the luminol. The manner in which it does this has been the subject of much speculation {2, 5, 21). According to recent ideas, the hydrogen peroxide may furnish free radicals to the solution {3-5, 9, 10, [16][17][18][19], which when reacting with the anion of the luminol in the presence of hemoglobin, produce a series of transient intermediate free radicals {2, 5-7, 12, 21) and the evolution of light from the final diradical {15).…”
