Formation and decomposition of hydrogen peroxide during UV-radiation, ozonization, and O3/UV treatment of river water

We have studied the kinetics of the formation of hydrogen peroxide during UV-radiation, ozonization, and O 3 /UV treatment of water of the Dnieper River and model solutions of fulvic acids. We have also investigated decomposition of added hydrogen peroxide at the indicated methods of treating river and model waters and the impact of H 2 O 2 on the concentration of dissolved ozone.
