Performance of polyphenylsulfone-based solvent resistant nanofiltration membranes in removing dyes from methanol solution
In this study, polyphenylsulfone (PPSU) which is a third member of the polysulfone (PSF) family, with even better properties than PSF and polyethersulfone (PES) was used to prepare flat sheet solvent resistant nanofiltration (SRNF) membranes. The SRNF membranes were prepared from different PPSU conc...
