Abstract

The choice of energy input rate in treatment of aqueous media with gas-phase pulsed corona discharge (PCD) requires quantification of reactive oxygen species (ROS) reactions dependent on oxidation kinetics. The role of surfactant and non-surfactant OH-radical scavengers in PCD was studied in respect of oxidation of phenol, oxalic and humic acid. Phenol reacts fast, whereas oxalate is known to selectively react with OH-radicals. Humic acid oxidation is slow. Rapid energy intake is advised for oxidation induced exclusively by radical reactions, such as humics, whereas abatement of admixtures reacting with both surface-borne and long-living oxidants benefits from reduced pulse repetition frequency.
