Abstract

The aim of this study was to compare of different approaches used to calculate the surface free energy(SFE) of polysulfone ultrafiltration membrane. SFE of polysulfone membrane was calculated by ZismanPlot (ZP), Equation of State (ES), Fowkes/OWRK (GM), Wu (HM) and van Oss-Chaudhury-Good (AB)approaches. The results of ZP and HM approaches were significantly different than the others (P<0.01).According to GM and AB methods, the total SFE values were 38.0±2.3 and 36.1±1.8 mN/m, respectively.No statistical difference observed between two approaches based on dispersive and polar components(P>0.01). However, AB approach provided more detailed information about electron-acceptor (1.0±0.7mN/m) and electron–donor (12.8±1.4 mN/m) components of the SFE. In conclusion, carrying out theanalysis of surface characteristics of a polymeric membrane with three different test liquids used in ABapproach have shown to be a more accurate way due to variation of characteristics of feed solutionsduring the separation processes

Özet

Bu çalışmanın amacı, polisülfon (PS) yapıda ultrafiltrasyon membranının serbest yüzey enerjisinin (SYE)hesaplanmasında kullanılan farklı yaklaşımların karşılaştırılmasıdır. PS membranın serbest yüzey enerjisi,Zisman Plot (ZP), Equation of State (ES), Fowkes/OWRK (GO), Wu (HO) ve vanOss-Chaudhury-Good(AB) yaklaşımları ile hesaplanmıştır. ZP ve HO yaklaşımları ile hesaplanan SYE sonuçları, diğeryaklaşımların sonuçlarından istatistiksel olarak farklı bulunmuştur (P<0.01). GO yaklaşımında toplamSYE 38.0±2.3 mN/m, AB yaklaşımında ise 36.1±1.8 mN/m hesaplanmıştır. İki yaklaşımın dağılım ve polarbileşen sonuçları arasında da istatistiksel olarak fark gözlenmemiştir (P>0.01). Ancak AB yaklaşımıyüzey enerjisinin elektron alıcı (1.0±0.7 mN/m) ve verici bileşenleri (12.8±1.4 mN/m) ile ilgili dahadetaylı bilgi sağlamıştır. Sonuç olarak ayırım prosesleri süresince besleme çözeltilerinin karakteristiközelliklerinde değişimler meydana geldiği için, polimerik yapıda membran yüzey özelliklerinin üç farklıtest sıvısıyla analiz edilmesinin daha doğru bir yaklaşım olduğu ortaya konulmuştur
