“…The weak effect of OXA concentration indicates that, under the study conditions, the oxidative species generated are sufficient to degrade the pollutant concentrations tested. These results are very similar to those obtained by González et al during the electrochemical degradation of trimethoprim using BDD anodes [39]. The Pareto chart also shows that interactions between the electrolyte concentration and the other two evaluated parameters are also significant, again indicating the important role of this variable.…”

Degradation rates and removal efficiencies of different parabens, namely, methylparaben, ethylparaben, propylparaben, and butylparaben using H 2 O 2 /Fe 2þ advanced oxidation process are studied in this work. With the aim of optimizing the removal of parabens from waters through the Fenton process, a factorial central composite orthogonal and rotatable design (FCCORD) was used. H 2 O 2 and Fe 2þ ion initial concentrations were selected as independent variables. The experimental procedure planned according to the FCCORD makes it possible to optimize the removal. The occurrence of interactions between these two variables can also be analyzed with the aid of the experimental design. Fenton process provides conversion efficiencies comprising between 85 and 94 % after a reaction time of 48 h, which reveals the appropriateness of this procedure for the removal of parabens from aqueous matrices.

“…In the literature, electrochemical oxidation of various organic pollutants was studied, and authors reported that increase in current density increased the removal of organic pollutants, COD removal, and energy consumption [17,[31][32][33][34][35]. Comninellis and Chen [10] and Panizza and Cerisola [12] reported that for high organic concentrations or low current densities, COD decreases linearly due to local concentration of Å OH relative to organics concentration on the anode surface, which is affected independently by organic pollutant nature, current efficiency, and the amount of intermediates.…”

A B S T R A C TElectrochemical oxidation and process optimization of sulfadiazine antibiotic were investigated in a batch electrochemical reactor using boron-doped diamond (BDD) anode. Reaction conditions were operated at 200-1,000 mg/L sulfadiazine concentration, 0-8 g/L supporting electrolyte (NaCl), 4-20 mA/cm 2 current density, and 25-45˚C reaction temperature at 120 min reaction time. Process optimization was accomplished through response surface methodology in central composite designed experiments. Optimum operating conditions were determined under specified cost-driven constraints at 13.4 mA/cm 2 current density, 618 mg/L sulfadiazine concentration, 3.6 g/L electrolyte concentration, and 36˚C reaction temperature. In a specific batch run at response surface-optimized conditions, the responses for sulfadiazine removal, COD removal, EOX, and energy consumption were achieved as 100.0%, 95.5%, 0.0617, and 94.3 kWh/kg COD r , respectively. Relative error values in this optimization study for the electrochemical oxidation of sulfadiazine antibiotic using BDD anode were obtained below 2%.
