بوليمرات الطبعة الجزيئية(MIPs) ل دي -ارابينيتول D-arabinitol غير التساهمية لتحديد كحول السكر المختلف
محتوى المقالة الرئيسي
الملخص
تعد البوليمرات التي تطبع جزيئيًا (MIPs) طريقة فعالة لفصل المركبات الطيفية. الهدف الرئيسي من هذا البحث هو تجميع D-arabinitol MIPs ، والتي يمكن أن تفصل بشكل انتقائي بين D-arabinitol وتطبيقه المحتمل لتمييزه عن مركب enantiomer الخاص به من خلال نهج غير تساهمي. تم تصنيع بوليمر ضخم باستخدام D-arabinitol كقالب ، الأكريلاميد كمونومر وظيفي ، إيثيلين جليكول dimethacrylate (EGDMA) كونه رابطًا متقاطعًا ، ثنائي ميثيل سلفوكسيد (DMSO) كان بوروجان ، وكذلك بنزويل بيروكسيد كونه بادئًا. بعد تصنيع البوليمر ، تمت إزالة D-arabinitol بمزيج من الميثانول وحمض الخليك (4: 1 ، v / v). يقوم التحليل الطيفي بالأشعة تحت الحمراء (FT-IR) والفحص المجهري الإلكتروني (SEM) بتمييز MIPs و NIPs. تم إجراء اختبار انتقائي لـ MIPs ضد enantiomers (L-arabinitol و xylitol و adonitol و glucose) باستخدام طريقة إعادة الدفعة. تم تحديد موقع الارتباط كمياً باستخدام معادلة لانجمير. أظهرت نتائج اختبار الانتقائية أن MIPs التي تم إنتاجها كانت انتقائية تمامًا تجاه enantiomer ويمكن استخدامها لفصل D-arabinitol عن enantiomer.
