dc.description.abstractIn this study, the electrochemical oxidation (EO) process was implemented and optimized to effectively decolorize and degrade wastewater containing Acid Yellow 23 (Y23). The experiments were carried out in a laboratory-scale batch cell reactor, with monopolar configuration of electrodes, made of graphite (anode) and titanium (cathode). The response surface methodology (RSM), coupled with Box-Behnken experimental design (BBD), was used to evaluate the single and interactive effects of different variables of the EO process on (1)degradation percentages of both chemical oxygen demand (%DCOD) and color (%DC) and (2)energy consumption (EC). Thus, the following experimental factors were considered: initial dye concentration (40-100mg/L), current density (10-20mA/cm2), and conductivity (1,000-4,000S/cm). Thus, the subsequent conditions were found to be optimal for decolorization and degradation of Y23: initial dye concentration = 100mg/L; current density = 20mA/cm2; and conductivity = 4,000S/cm. At these conditions, the EO process allowed to reach approximately 99% of color degradation and 76% of COD degradation. Because NaCl was used as an electrolyte, chorine formation was monitored, and its effect on %DC and %DCOD was also evaluated.eng
