For the purpose of using membranes from polysulfone (PSF) for oxygen enrichment, were prepared by dry/wet method. This method was involved in evaporation step air followed an immersion into a water bath. Then thin top layer asymmetric membrane formed step. There are three experimental parameters that influce formation including polymer concentration, time, and ratio tetrahydrofuran (THF)/N-methylpyrrolidone (NMP) studied. From experiments, some results showed high selectivity coefficient 1,53 at 0,1 MPa pressure with flow through 0,310ml/s.
