Evaluation of Fenton and Ozone Treatment Process for the Degradation of Psychiatric Drugs Carbamazepine (CBZ) and Oxcarbazepine (oxCBZ) in Simulated Waste Water (SWW)

The current research focuses on the evaluation of two advanced oxidation processes (AOPs) viz. Fenton and ozone treatment for the degradation of recalcitrant antipsychiatrics carbamazepine (CBZ) and oxcarbazepine (oxCBZ) in simulated wastewater. The parameters for Fenton reactions viz. pH, Fenton dosage, contact time and Fe2+/H2O2 were optimized using Response Surface Methodology. The optimum conditions obtained were (pH 2.0, Fenton dosage 1.61 g/dm3, Fe2+/H2O2 0.427 and contact time of 25 minutes) which yields a COD destruction of 92.49%. A pseudo-first order rate constant of 0.6185 min-1 and 0.0676 min-1 was observed for the ozonation of CBZ and oxCBZ respectively
