A Study of the Performance of Dielectric Barrier Discharge under Different Conditions for Nitrobenzene Degradation
Water scarcity and water contamination due to the extensive use of organic compounds in industries trigger us to adopt modern techniques for wastewater treatment. In this research, we developed a new dielectric barrier discharge (DBD) system which was evaluated for the degradation of nitrobenzene in...

The energy yield of the DBD system was 1.253 mg/kWh for the degradation of 20 mg/L of NB to 75% in 60 min with the discharge power of 0.538 W, which displays better results in comparison with the other AOPs regarding energy yield and the degradation efficiency of the pollutant. The results illustrate the significance of the system and further suggest its application to industrial-scale treatment.https://www.mdpi.com/2073-4441/11/4/842dielectric barrier dischargeactive speciesadvanced oxidation processesnitrobenzeneenergy yield |
