چکیده
Electrocoagulation on an industrial wastewater using Fe and Al electrodes was investigated in the present work. The goal was to inspect the parametric removal of COD from an industrial wastewater with the focus on both Al and Fe electrodes. The effects of current density, inter-electrode distance, electrocoagulation duration, and initial pH were evaluated. Results showed that in all cases, Fe electrodes removed COD more efficiently. With only 2 plates of Fe electrodes and durations of 15 min only, except for the time-assessed experiments, COD removal efficiencies of %35, %45, and %36 were found for 0.5 cm of electrode gap, 1000 A/m2 of current density, and pH of 4.2. Results for Al electrodes were %28, %43, and %35, respectively. The best results for EC duration were found at 45 and 30 min of EC for Fe (%43) and Al (%32), respectivelyکلیدواژه ها

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.
