Abstract :In this study, pH and ΔpH change in the electrochemical oxidation of imidacloprid insert ignore into journalissuearticles values(IMD); pesticide using boron-doped diamond insert ignore into journalissuearticles values(BDD); electrodes was investigated in the presence of Na 2 SO 4 electrolyte. The process parameters were operated as imidacloprid concentration insert ignore into journalissuearticles values(40-200 mg/L);, electrolyte concentration insert ignore into journalissuearticles values(2-10 g/L);, current density insert ignore into journalissuearticles values(4-20 mA/cm 2 ); and reaction temperature insert ignore into journalissuearticles values(20-60°C);. pH and ΔpH values increased with increasing Na 2 SO 4 concentration, current density, and reaction temperature, and decreasing the imidacloprid concentration at 120 min reaction time. The results of this study showed that the pH of the wastewater solution maintained the local pH discharge limits between 6 and 9 after the electrochemical oxidation.
