چکیده:

Asymmetric ultrafiltration membranes were prepared by phase inversion from mixtures containing nylon 66 as the main polymer, formic acid as solvent, acetone, PVP, and ammonium oxalate (OX) as additives and water as non-solvent. The effects of various drying procedure on performance and morphology of polyamide membrane were studied. The performance of membranes was characterized in terms of separation
behavior using milk as the feed. The structures of membranes were elucidated by electron microscopy
