چکیده

Introduction: Acetamiprid (AP) is one of the most widely used pesticides in the neonicotinoid class. AP residues in the environment have received considerable due to their potential toxicity to humans. Therefore, it is important to remove AP from the aqueous solution. Materials and Methods: In the current study, response surface methodology (RSM) was used as an efficient approach to optimize the removal of AP using the electro-Fenton (EF) process. The effects of the main variables, including reaction time, AP concentration, current density, and H۲O۲ dosage were investigated and optimized. ANOVA technique was also used to identify the Fisher’s value (F-value) and P-value of the model. Results: The predicted AP removal efficiency by the model was in good agreement with the obtained experimental results with correlation regression of ۰.۹۸. The ANOVA test proved that the developed quadratic model was significant with very low P-values less than ۰.۰۵, the high F-value of ۲۴۰.۱, and regression coefficients close to ۱ at a ۹۵% confidence level. The optimum condition for AP removal efficiency of ۹۹.۰۲% was attained at the reaction time of ۱۲ min, AP concentration of ۳.۵ mg L-۱, the current density of ۱۲ mA cm-۲, and H۲O۲ dosage of ۸۶ µL. Conclusion: RSM was employed as a suitable method to optimize the operating condition and maximize the AP removal. Herein, the EF process as an eco-friendly electrochemical advanced oxidation process (EAOP) successfully applied to remove AP from the water and wastewater.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
