Ozmotik Distilasyonda Polisülfon-g-Polistiren/Selüloz/Poli (etilen teraftalat) Kompozit Membranların Kullanılması

Bu çalışmada fruktoz çözeltileri ozmotik distilasyon yöntemi kullanılarak, polisülfon-g-polistiren (PSf-g-PS) aşı kopolimerlerinin selüloz/poli(etilen teraftalat) (CV/PET) ile hazırlanmış olan kompozit membranlarla deriştirilmesi çalışılmıştır. Membranlar faz dönüşümü yöntemi ile hazırlanmış ve Taramalı Elektron Mikroskopisi (SEM) ile karakterize edilmiştir. Besleme ve brine çözeltileri sirkülasyon hızları ve derişimleri, brine çeşidi ve sıcaklık gibi çeşitli proses parametrelerinin akı üzerine etkileri araştırılmıştır. Besleme ve brine çözeltisi sirkülasyon hızlarındaki artış akıyı önce belirli bir sirkülasyon hızına kadar artırıp, daha sonra azaltmıştır. Brine çözelti derişiminde en yüksek akı doygunluğa yakın olan derişimde gözlenmiştir. En yüksek akarım MgCl2’ de elde edilmiştir.

Anahtar Kelimeler:
