Abstract

Ultrafiltration membranes based on anion charged poly(bis[4-(3-aminophenoxy)phenyl]sulfone pyromellite) imide derivatives (ACPI) were prepared by the phase inversion method. The polymers have good solubility in aprotic polar solvents. The composition of casting solution and the casting conditions played an important role in determining the permeation characteristics of membrane because the membrane structure could be controlled by the preparation conditions. The extent of fouling-repression was observed by the relative ratio of permeate flux ($J_t$)/pure water flux ($J_0$) and the membrane filtration index (MFI). The characteristics were measured by aqueous solution of bovine serum albumin (BSA) over a pH range of 2.5-9.0. The ACPI membrane having a hydrophilic property was less fouled than the membrane prepared from the original polyimide. With increasing the ion exchange capacity of ACPI membrane, th $\varepsilon$ relative ratio of flux was higher while the membrane filtration index was lower as compared with the original polyimide membrane. From the further away from isoelectric point of bovin serum albumin, the permeation was higher as well as the formation of fouling was more diminish. ACPI membranes having various their properties could be obtained. Further, it was proved that their permeation properties could be determined from the preparation conditions, various operating conditions, and dim $\varepsilon$ rent ion exchange capacity of anion charged polyimide derivatives.

상전환 방법으로 제조된 음이온 성 Poly(his[4-(3-aminophenoxy)phenyl]sulfone pyromellite)imide(ACPI) 한외여과막의 순수 투과유속과 용질 배재도 측정치로 투과성능을 연구하였다. ACPI 한외여과막의 투과성능은 캐스팅 용액의 조성과 막 제조 및 측정조건에 영향을 받았다. Bovine serum albumin (BSA) 용액을 pH 2.5-9.0 상태에서 ACPI 한외여과 막의 상대투과유속과 membrane filtration index (MFI) 측정한 결과 BSA의 등전점에서 멀어 질수록 상대투과유속은 증가하고 막 오염정도를 나타내는 MFI는 감소하였다. 또한, 친수성인 ACPI 한외여과막의 이온교환용량(IEC)이 증가할수록 상대투과유속은 증가하고, MFI는 감소하였다.
