Effect of solution conductivity on H202 production by pulsed corona discharge in water

Summary form only given. Non-equilibrium plasma generated by electrical discharges in liquids initiate various chemical and physical processes that can be potentially utilized in different environmental, biological or medical applications. These processes include high electric field, ultraviolet radiation, overpressure shock waves and, of particular importance, formation of various reactive chemical species such as radicals (OH, H, O) and molecular species (H₂O₂, H₂, O₃), among which OH radicals and hydrogen peroxide are the most important for oxidation processes. The magnitude of the contributions of the individual effects in the decontamination or microbial inactivation processes strongly depends upon the energy of the discharge and also on the solution conductivity.
