Determination of quinones by a chemiluminescence reaction in solution.
Oxidation of p-benzoquinone by hydrogen peroxide in an alkaline medium gives chemiluminescence emission with maximum intensity at 660 and 560 nm. 1,4-Naphthaquinone gives only a single maximum at 660 nm. These emissions can be used for the determination of microg amounts of the quinones. The interference effect of some organic compounds is described.
