Time dependence of the concentration of dissolved ozone in water generated by dielectric barrier discharge (DBD) plasma using atmospheric air

Ozone is one of the reactive oxygen species that can be produced from plasma. In this study, the ozone was generated by using a dielectric barrier discharge (DBD) plasma technology. DBD plasma was generated using two electrodes separated by a glass dielectric isolator and an alternating current (AC)...

Description
Summary:Ozone is one of the reactive oxygen species that can be produced from plasma. In this study, the ozone was generated by using a dielectric barrier discharge (DBD) plasma technology. DBD plasma was generated using two electrodes separated by a glass dielectric isolator and an alternating current (AC) voltage source of 5 kV with an airflow rate of 1 L/min at room temperature and atmospheric pressure. In this study, the ozone concentration was determined using the titration method. The ozone concentration was measured by varying the titration time between 0-10 minutes. The time dependence of ozone concentration in water tends to follow the polynomial trendline. The longer plasma treatment was performed, the higher ozone concentration was measured. The ozone significantly increased when the treatment was conducted for more than 6 min.
