Abstract

الخلاصــــة
   تزايدت المخاوف بشأن تلوث البلاستيك والجسيمات البلاستيكية المايكروية والمخاطر التي تشكلها على البيئة. لا تستطيع محطات معالجة المياه إزالة الجسيمات البلاستيكية المايكروية بكفاءة، مما يجعل المياه الناتجة عنها مصدرًا رئيسيًا لتلوث البيئة المائية. في هذه الدراسة، تم استخدام مفاعل الدفعة لدراسة التحلل الضوئي لجسيمات البلاستيكية لبولي فنيل كلوريد المايكروي في محلول مائي بواسطة دقائق الحديد النانوية  المصنعة من مستخلص قشور الرمان كعامل محفز وتحت اشعة الشمس .قبل وبعد عملية التحلل الضوئي، تم فحص سطح الدقائق الحديد النانوية والبولي فينيل كلوريد المايكروي باستخدام المجهر الإلكتروني الماسح (SEM) وطيف الأشعة تحت الحمراء باستخدام تحويل فورييه .(FTIR) وتم أستخدام منهجية الاستجابة السطحية (RSM) وتصميم المركب المركزي (CCD)، لتقييم العوامل التشغيلية الرئيسية التي تؤثر في كفاءة التحلل. أظهرت الدقائق الحديد النانوية نشاطًا تحفيزيًا ضوئيًا عاليا، حيث تمت إزالة 95% من البولي فينيل كلوريد المايكروي تحت الظروف المثلى، (تركيز محفز قدره 50 ملغم/لتر، 5 ملغم من  بولي فينيل كلوريد، الأس الهيدروجيني3، وفترة تفاعل قدرها 30 يومًا) .تطابقت تنبؤات نموذج تصميم المركب المركزي بشكل وثيق مع البيانات التجريبية، مما يوكد دقته وفعاليته. تسلط هذه الدراسة الضوء على إمكانية استخدام دقائق الحديد النانوية المُصنَّعة بطريقة صديقة للبيئة كحل مستدام وصديق للبيئة لمعالجة تلوث المياه بالجسيمات البلاستيكية المايكروية  .
