Optimization of the operating parameters using RSM for the Fenton oxidation process and adsorption on vegetal carbon of MO solutions

This study focused on the application of RSM on the Fenton process and the adsorption of vegetal carbon (VC) to obtain the optimal conditions for the minimization of the colored synthetic wastewater. Methyl orange (MO) with an azo dye was used as the model organic compound. Fenton processes were investigated to establish the optimal conditions. The Fe2+/H2O2 ratio was studied to establish the major MO degradation when 100 and 200 mg/L of MO were treated. For the adsorption process, to determine the optimal conditions, the principal variables studied were the vegetal carbon mass dosage, degradation time and dye concentration.
