The full factorial design of experiment was used to explore the influence of operational variables such as pH, initial concentration of hydrogen peroxide and Ferrous ions on the removal of COD. The analysis of variance (ANOVA) showed a high determination coefficient value (R2 = 0.9884, R2pred = 0.9713, R2adj = 0.9822) for removal of COD and satisfactory prediction second-order regression model. The graphical response surface plots were employed to determine the optimum conditions. The operational variables were optimized by the model as follows: the [Fe2+] = 24 mg/L, pH at 3, and [H2O2] = 500 mg/L. The results showed that at the predicted optimum conditions and after 60 min of reaction, the degradation (removal of COD) and mineralization (removal of TOC) were 76.1 and 68.7%, respectively.}, number={4}, journal={International Journal of Industrial Chemistry}, publisher={OICC Press}, author={Shokri, Aref}, year={2023}, month={Nov.}, keywords={Degradation, Mineralization, Fenton process, Phenolic compounds, Photo, Response surface plots, Sono} }
