Popis: A double cylindrical dielectric barrier discharge (DCDBD) was optimised and coupled with SS/C-N-TiO2 photocatalysts produced by sol gel technique for the treatment of orange II (O.II) dye. The results show that degradation of 60 mg/L O.II with both systems followed first-order reaction. Higher removal of O.II was achieved with DCDBD-SS/C-N-TiO2 technology. The decomposition of O.II resulted in six and four degradation metabolites with DCDBD alone, and DCDBD-SS/C-N-TiO2, respectively. The COD and TOC removals reached 61.43% and 15.38%, respectively after 60 min of DCDBD run. This study demonstrates that DCDBD is a promising advanced technology for the treatment of dye wastewater.
