Abstract:
Combination of electro-Fenton (EF) oxidation process with sonication for both the degradation of C.I.
Reactive Black 5 (RB 5) and removal of chemical oxygen demand (COD) from synthetic textile
wastewater was investigated under different operating conditions. Optimal conditions were found as the
initial pH of 3, DC current of 0.25 A, H2O2 dosage of 800 mg/L and electrode distance of 2.5 cm for both EF
and ultrasound assisted electro-Fenton (sono-EF) processes. However, the combination of EF with
sonication was negligibly improved in terms of COD and color removals, compared to EF process.
