- Abstract
- This rapid communication reports a summary of the key findings of preparation and characterization of new polymeric
membranes for nanofiltration of organic compounds. A series of nanoporous asymmetric membranes of PEEKWC, a
modified poly(etheretherketone) was prepared by means of the dry-wet phase inversion method. In particular, the type
and concentration of internal non-solvent were varied in order to obtain membranes for nanofiltration. The optimization
of these factors led to reproducible membranes, which were characterized for hydrophobicity, roughness, morphology, surface
charge. The performance was studied by doing dead-end filtration experiments with aqueous solutions of uncharged
and charged organic compounds. The new polymeric films exhibited interesting performance compared to commercial
nanofiltration membranes in terms of retention and relative flux for positively charged organic compounds.
