摘要

In this study preparation of polyphenylsulfone (PPSU) flat sheet and hollow fiber nanofiltration membranes was investigated. Flat sheet membranes were prepared based on phase inversion method with different concentrations of PPSU (17%, 21% and 25% W/W) in dimethylacetamide (DMA), N-methyl-2-pyrrolidone (NMP) and a mixture of dimethylformamide (DMF) and NMP.
