Abstract
Environmentally persistent organic pollutants have become a concern to the sustainability of the environment, and many of them are harmful to human health. This work explores the feasibility of a low-temperature plasma-based technology for the degradation of organic pollutants such as Rhodamine-B (Rh-B) in water. Applying 300-ns, 20 kV pulses at 500 Hz to a strip line-like electrode configuration, sliding discharges are generated at the gas-water interface in one atmospheric air or nitrogen above contaminated water. An average Rh-B reduction of 30% and 19% were achieved with air and nitrogen, respectively, when 20 mM of Rh-B solution flew through the reactor at a flow rate of 1 mL/s. Over 90% degradation of Rh-B was obtained after 9 cycles of treatment of the plasma operated at 0.12 J per pulse or an average power of 60 W using ambient air as the working gas. This work demonstrates that the nanosecond sliding discharge-based plasma reactor is a promising technology for removing organic pollutants from wastewater.
