Abstract Studies of the rates of decomposition and photoproduction of hydrogen peroxide (H2O2) by several green and blue-green algae in water are reported. Results suggest that algae have an important influence on the environmental concentration of H2O2, a widely distributed oxidant in natural waters. The algal-catalyzed decomposition of H2O2 in the dark was found to be second-order overall, first-order with respect to H2O2, and first-order with respect to algal biomass. Exposure of algal suspensions to sunlight resulted in a build up of H2O2, indicating that algae can photoproduce as well as decompose the oxidant. Kinetic results for the algal-induced photooxidation of substituted anilines are presented and a mechanism involving the intermediacy of H2O2 is discussed.
