حضر نوعين من قواعد شف من تكاثف (2,4-dihydroxybenzaldehyde) ، (4-hydroxy Benz aldehyde) مع 3-amino phenol)) على التوالي وشخصت الليكندات المحضرة بمطيافية الاشعة تحت الحمراء (FT-IR (وطيف الرنين النووي المغناطيسي(HNMR1)، وشخصت المعقدات المتكونة مع الحديد الثلاثي لكل من الليكندات المحضرة بمطيافية (UV- VIS (حيث أعطى المعقد الأول ( L1Fe ( أزاحة حمراء أمّا المعقد الثاني(L2Fe (اعطى إزاحة زرقاء مقارنة مع طيف الليكاند المحضر على التوالي ،من ثم حضرت رغوة البولي يوريثان وطعمت بقواعد شف المحضرة للحصول على بوليمر كلابي) R1،R2) وتم تشخيص الراتنج المحضر بمطيافية الأشعة تحت الحمراء (FT-IR) وتقنية التحليل الحراري الوزني ) TGA, DSC).
ركز هذا البحث على دراسة الكفاءة التحليلية للسطح المحضر باتباع طريقة الوجبة Batch method تحت الظروف المثلى كزمن الاتزان والدالة الحامضية وطبقت النتائج عمليًا على عينة مياه الصرف الصحي، حيث أظهرت النتائج الحصول على نسبة إزالة عالية لأيون الحديد الثلاثي وبلغت 100%مما يدل على إمكانية استخدام البوليمرات الكلابية المحضرة على مدى واسع لإزالة التلوث لأيون الحديد الثلاثي مما يؤدي في النهاية الى تحسين جودة معالجة مياه الصرف الصحي.
