Abstract
|
Blend membranes of polycarbonate and polysulfone were studied for removal of bovine serum albumin (BSA) from water. The membranes were prepared by blending (1-10) wt.% of polysulfone with polycarbonate and then non-solvent induced phase separation (NIPS) of blend solutions. Structural analysis, thermal and tensile properties, water uptake, porosity, water contact angle, and morphological studies were conducted. Water treatment performance of membranes were tested in a crossflow system in terms of pure water flux, rejection, and fouling. BSA rejection value was improved from 85.65 to 92.88% for polycarbonate membrane in the presence of 10 wt.% polysulfone.
