Analytical applications of peroxyoxalate chemiluminescence

Peroxyoxalate chemiluminescence can be applied to the determination of hydrogen peroxide and aromatic hydrocarbon fluorophores in a static system. Hydrogen peroxide causes a linear response in the range 10^-6–10^-1M when bis(2,4,6-trichlorophenyl) oxalate is used with perylene as the fluorophore. As the intensity of chemiluminescence from different aromatic hydrocarbons varies substantially, there is a degree of selectivity in their determination. If metal chelates are employed as fluorophores, trace metal analysis is possible.
