Abstract

Background: DIAZINON is one of the most important pesticides extremely used in agriculture. Since these compounds are resistant to biodegradation, the arrival of these compounds to water resources has become a serious environmental problem. Therefore, in the current work, the REMOVAL of DIAZINON from GROUNDWATER was investigated using advanced oxidation processes ELECTRO FENTON.Methods: the current work was conducted in lab scale. The effect of operating parameters such as initial concentration of DIAZINON (1-30 mg.L-1), pH solution (3-9), current density (1-10 mA.cm-2), reaction time (3-30 min), and dosage of H2O2 (20-100 mL.L-1) were investigated. RESPONSE SURFACE METHODOLOGY (RSM) was used to optimize the parameters and suggested model was analyzed using ANOVA.Results: On the optimum condition including initial DIAZINON concentration of 6.88 mg.L-1, pH solution of 3, the reaction time of 10 min, the current density of 8.18 mA.cm-2, and dosage H2O2 of 83.78 mL.L-1 REMOVAL efficiency of DIAZINON was found to be 98.5 %. Electrical energy consumption (EEC) was found to be 0.524 kWh.m-3. Moreover, the concentration of DIAZINON in GROUNDWATER was found to be 0.934±0.053 mg.L-1.Conclusion: According to the obtained results, ELECTRO FENTON process was found to be an efficient technique for successful REMOVAL of DIAZINON and other resistant ungradable organic compound from water sources.
