Abstract
Fouling–resistant cellulose acetate (CA) membranes were prepared by the phase inversion technique using hydrophilic aminated polyethersulfone (APES) as the modification agent. In the presence of polyethylene glycol 600 as a pore forming agent, were blended in 100/0,90/10,80/20,70/30% compositions using N,N‟- dimethylformamide as solvent. The cellulose acetate/aminated polyethersulfone membranes were applied for proteins separations. The performance of the blend membranes of various blend polymer compositions were compared with that of membranes prepared from pure cellulose acetate and blends of cellulose acetate and aminated polyethersulfone. The hydrophilic blend ultrafiltration membranes showed better performance compared to pure cellulose acetate
