Diazinon (DZ), an organophosphorus pesticide, has a large consumption for agricultural
activities, which its discharge into groundwater and surface is associated with serious
concerns for the animal and plants. Thus, the degradation of the mentioned pesticide from
an aqueous environment was examined in the electro-Fenton (EF) and sono-electro-Fenton
process (SEF) process using SS316/β-PbO 2 anode. To characterize the synthesized
anode, the analyses, eg, XRD, SEM, and EDX, were used. The central composite design …

This study investigates the feasibility of applying electro-Fenton (EF) and sono-electro-
Fenton (SEF) processes for the removal of chemical oxygen demand (COD) from the
hospital wastewater generated by the Al-Diwaniyah hospital located in Iraq. The effect of
various operational parameters on COD removal was studied based on the response
surface methodology (RSM). The optimal conditions for maximum removal of COD using EF
were found to be a current density of 19.293 mA/cm 2, an H 2 O 2/COD ratio of 1.4, and a …
