Study of the mimetic peroxidase-catalysed chemiluminescence reaction

The chemiluminescence behaviour of the reaction in which the Mn-TPPS₄ complex the mimetic enzyme of peroxidase manganese tetrakis(sulphophenyl)porphine] acts as a catalyst for the oxidation of luminol by hydrogen peroxide was studied. The reaction product luminesces at 427 nm. Trace amounts of hydrogen peroxide and glucose can be determined with detection limits of 5.5 × 10^?9 and 2.7 × 10^?9 M, respectively. The characteristics of Mn-TPPS₄ were compared with those of horseradish peroxidase.
