Abstract

In this paper, Diclofenac sodium drug removal was studied by electro-Fenton process, and utilizing an iron electrode to engender Fe2+ ions in a batch reactor. In order to reach the maximum efficiency of the process, efficacious parameters such as: NaCl, H2O2, electrode distance and electrolysis time were investigated. The experimental data designated that all operational parameters played a paramount role in the process. High R2 (82.24%) drug removal, (84.69%) COD abstraction by Fenton like advanced oxidation process, is exhibiting the efficacy of the model. The 80% drug and 91% COD removals were observed at optimum levels of factors. The kinetic study of the drug removal was also performed.
