چکیده

Background: Aniline-based organic nanocomposites have a significant performance as photocatalysts in the advanced oxidation process (AOP).Methods: In this study, polyaniline-tin dioxide (PA/SnO۲) nanocomposite was prepared using an ultrasonic process. Next, its efficiency as a photocatalyst in the removal of Cefixime antibiotic pollutant from contaminated waters in a tubular photo reactor was investigated. The experiments were designed by the response surface methodology (RSM) via Minitab software, in such a way that the effects of various parameters on the process are investigated. The effect of different parameters such as reaction time, solution pH, flow rate, antibiotic concentration and hydrogen peroxide concentration on the removal efficiency was investigated.Results: According to the results, the following optimal conditions were obtained: time of ۱۲۰ min, pH of ۸.۶۹, hydrogen peroxide concentration of ۴.۲۲ mM, flow rate of ۱.۲۵ L/min and initial antibiotic concentration of ۲۲.۹۲ mg/L. Under the above-mentioned optimal conditions, the efficiency of Cefixime removal was more than ۷۲.۲۴%.Conclusion: The present study confirms the usability of the PA/SnO۲ nanocomposite as a novel and effective photocatalyst for photocatalytic degradation of Cefixime antibiotic in contaminated water under UV light.

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.
