چکیده

در این‌مقاله، ازن‌زنی و ازن‌زنی همراه با کربن فعال به‌منظور حذف مادۀ دارویی سفکسیم از محیط­های آبی مورد مطالعه قرار گرفت. نتایج آزمایش ازن‌زنی بر سفکسیم نشان داد که ازن‌زنی بر روند حذف سفکسیم از محلول آبی تأثیر مثبت دارد، به‌طوری‌که غلظت آلایندۀ دارویی در مدت زمان 30 دقیقه از ppm 55به ppm 6 کاهش یافت. همچنین مؤلفۀ COD نیز به‌میزان 51% کاهش پیدا کرد. تأثیر استفاده از ازن همراه با کربن فعال، برای غلظت مشخصی از آلایندۀ دارویی ثابت شد. تأثیر مؤلفه‌های عملیاتی مختلف از قبیل میزان غلظت آلایندۀ دارویی، غلظت کربن فعال، میزان غلظت ازن ورودی، زمان واکنش و pH
بر روی فرایند ازن‌زنی همراه با کربن فعال بررسی شد. حداکثر بازده حذف سفکسیم از محیط‌های آبی به‌میزان 96% محاسبه گردید. این مقدار در
pH خود محلول و در حدود 4 به‌دست آمد.
