Experimental Study and Response Surface Methodology Optimization of Electro-Fenton Process Reactive Orange 16 Dye Treatment
The batch mode electro-Fenton advanced oxidation process was used for Reactive Orange 16 (RO16) dye treatment. The work aimed to study and optimize the governing operational parameters (operational pH, A; initial RO16 concentration, B; electrolysis time, C; and current density, D) for decolorization and COD removal. Response surface methodology (RSM) was used for optimization. At optimum conditions (A = 3.5, B = 135 mg/L, C = 42.5 min, and D = 17.5 mA/m2), the results show decolorization and COD removal as 72% and 61%, respectively. The Pareto graph and ANOVA results confirmed that the process was most significantly affected by current density followed by pH value and total electrolysis time; whereas the higher initial dye concentrations (> 135 mg/L) adversely affected the process efficiency. Perturbation plots support the finding of results and diagnostic plots represent a good agreement with the experimental data. The kinetic study revealed the process best represented by the pseudo 2nd order kinetics (R2 = 0.9878); whereas, the total operational cost ($1.90 m−3) indicates an economical treatment of RO16 dye-bearing Textile effluent.
