- Abstract
- Polymeric nanofiltration membranes were prepared modifying via low temperature plasma treatment
flat membranes based on a modified poly(ether ether ketone) (PEEKWC). PEEKWC membranes, prepared
using wet phase inversion using methanol (M2m) and 1-butanol (M2b) as internal non-solvent, were further
plasma surface modified (RF 13.56 MHz) introducing amino groups on the membrane using two different
pre-treatment gases, Ar (M2bpsm/Ar/NH3 and M2mpsm/Ar/NH3) and H2 (M2bpsm/H2/NH3 and
M2mpsm/H2/NH3). The performances of unmodified and plasma modified membranes M2b and M2m
and of a commercial nanofiltration membrane (NFTFC50) were tested in treatment of aqueous solution
containing two dyes, characterized by similar molecular weight (?320 g/mol) and opposite charge, methylene
blue and methyl orange, positively and negatively charged, respectively. The observed rejections
resulted optimized in terms of fouling for the plasma modified membranes with respect to unmodified
and commercial NFTFC50 membranes. In particular, methylene blue was retained for 100% by
M2mpsm/Ar/NH3 with a relative flux of 100% compared to 100% and 95% rejections and 85% and 90% relative
fluxes observed for unmodified PEEKWC M2b membrane and commercial NFTFC50, respectively. (literal)
