• Casting process
• polysulfone membrane
• micellar solution bath
• narrow pore size distribution

The study reports the preparation of polysulfone membranes of very precise and uniform pores and pore size distribution. The concentration of N,N-dimethylformamide (DMF) and sodium dodecyl sulphate (SDS) surfactant in the coagulation bath played a vital role in pore formation during phase inversion process. Polysulfone membranes of narrow pore size distribution with median pores at about 0.04-0.06. mu m were obtained.
