This study aimed to understand the electro-Fenton-persulfate (EF/PS) system using fluoxetine (FLX) as a model contaminant. It examined the effects of Fe/PS molar ratio and current density through a central composite design. The study also explored how various factors like anode type, water matrix complexity, and pH impact the toxicity of the effluent. A kinetic model outlined the oxidation pathways and treatment strategies, highlighting the EF/PS process's benefits for FLX removal regarding energy efficiency and cost reduction. Optimal conditions (Fe/PS molar ratio = 0.59 and j = 53 mA cm-2) achieved complete FLX degradation in 5 min with no residual toxicity. The feasibility of applying the process to real water matrices at near-neutral pH was demonstrated, emphasizing the suitability of the DSA anode. Furthermore, the kinetic parameters obtained through mathematical modeling provide essential data for designing and configuring electro-Fenton/PS-oriented reactors and treatment systems for pharmaceutical wastewater impacted by the antidepressant. Finally, this work integrates kinetic modeling and toxicity assessment into the EF/PS framework, offering a promising, cost-effective approach for water remediation. (AU) | |
