ملخص المقالة :
در اين کار تحقيقی حذف يك آلايندة دارویی تحت عنوان دیکلوفناک (DCF) با استفاده از فرآيند UV/TiO2در يك فوتوراكتور ناپیوسته با بستر ثابت مورد بررسی قرار گرفته و شرایط عملیاتی موثر در کارآیی فرایند به روش سطح پاسخ (RSM) از نوع طراحی ترکیب مرکزی (CCD) بهینه‌سازی شده است. نتايج طراحي آزمايش نشان‌دهنده اثر مثبت پارامترهاي زمان تابش نور، دبي حجمي و اثر منفي پارامترهاي غلظت اوليه DCF و pH در راندومان حذف آلاینده مورد نظر (DCF) از محیطهای آبی مي‌باشد. همچنین از پارامترهاي مؤثر در راندمان حذف، بيشترين تأثير مربوط به پارامترهای زمان تابش و pH مي‌باشد. مقدار pH بهینه برای حذف DCF در فرایند مذکور حوالی 5/4 می‌باشد.
