Removal of Organic Contaminant from Wastewater by Applying Fenton Oxidation

This study investigates the effectiveness of Fenton oxidation in treating diethylamine (DEA) contamination in a batch reactor, emphasizing the optimization of key operational parameters. Factors such as reaction time, pH, ferrous ion concentration, and oxidant dosage were systematically analyzed to maximize performance. DEA degradation efficiency significantly improved with extended reaction times (30 min–3 h). Optimal conditions were established at pH 3.0, Fe²⁺ concentrations of 0.77–3.1 g/l, and oxidant dosage of 0.78 g/l. Hydrogen peroxide demonstrated superior performance under these parameters, particularly at 1.5 g/l Fe²⁺.The process achieved a maximum DEA removal efficiency of 83.7%, assessed through chemical oxygen demand (COD) reduction, while minimizing ammonia production (9.5%) and other by-product formation. These findings highlight Fenton oxidation as a promising and sustainable approach for addressing diethylamine pollution in industrial wastewater.
