The stopped-flow technique is evaluated for the determination of hydrogen peroxide based on the generation of chemiluminescence by the cobalt-catalyzed oxidation of luminol. Methods based on direct rate measurements on the formation and decay steps of the chemiluminescence process are compared with those involving conventional peak height or peak area measurement. The rate methods result in better precision or selectivity. The detection limit is 5×10-9M (25 pmol) and the sample throughput 60 h-1. An improved method for determining the formation and decay rate constants based on a fitting program is reported. © 1989.
