Filtrasyon Membranları Üretim ve Karakterizasyon Yöntemleri

Bu çalışma, teknolojik arıtma ve saflaştırma sistemlerinde son yıllarda yoğun bir şekilde kullanılan filtrasyon membranlarının üretim ve karakterizasyon yöntemleriyle ilgili bilgiler içermektedir. Sıvı faz ayırma sistemlerinde kullanılan ultrafiltrasyon membranlarının etkinliğinin artırılması için faz dönüşüm prensibine dayalı asimetrik yapıda üretilen membranların üretim koşulları ve membranlara fonksiyonellik kazandırmak için yapılan yüzey modifikasyon işlemleri tartışılmaktadır. Elektrostatik kuvvetlere dayalı zıt yüklü polielektrolitler ile yüzeyin kendiliğinden kat-kat kaplanmasının biyo-makromolekül immobilizasyonu için stabilitenin uzun süreler korunabilmesi ve bu tabakaların dinamik koşullarda akışa karşı önemli bir direnç gerçekleştirmemesi yöntemin avantajları arasında sıralanmaktadır. Yüzey modifikasyon işlemlerinin gerçekleşip gerçekleşmediğiyle ilgili uygulanan karakterizasyon metotları ayrıntılı bir şekilde değerlendirilmektedir.

Fabrication and Characterization Techniques of Filtration Membranes

This study includes knowledge about fabrication and characterization of filtration membranes which has been recently used intensively in technological treatment and purification systems. In order to enhance the effectiveness of the ultrafiltration membranes used in liquid phase separation processes, the fabrication conditions of the asymmetric membranes produced by the phase inversion principle and surface modification treatments for providing functionalities to the membranes are discussed. For the bio-macromolecules immobilization, protecting stabilities in a prolonged time and the negligible resistance of the layers against flux under dynamic conditions are among the advantageous of the layer-by-layer self-assembly which is based on the electrostatic forces between oppositely charged polyelectrolytes.  In order to understand whether or not the surface modification treatments are successfully achieved, the characterization methods applied are discussed in detail.
