Heterogeneous photo-electro-Fenton oxidation (hPEF) is known to be a robust technique, which can be employed for promoting organic degradation. This paper describes an environmentally friendly approach with the combination of photocatalysis and electrocatalysis in less acidic pH, aiming to achieve faster mineralization of a pharmaceutical micropollutant without adding any external oxidants. TiO2/GO/loaded Ag non-active electrodes are synthesized for the degradation of bupropion hydrochloride (antidepressant drug). The present work also seeks the parametric modeling and optimization of hPEF process parameters by using R programming. Nonlinear kinetic modeling was performed for the determination of kinetic parameters. The role of selected process parameters on the mineralization of bupropion was also explained in detail. The OH• and O2•− showed their active participation in the degradation process, while Ag and UV-C played an active role in the disinfection of treated wastewater.
