- Abstract
Polyvinyledenefluoride-polystyrene (PVDF/PS) blend ultrafiltration membranes were prepared using phase inversion
technique. Casting solutions were prepared with different compositions of poly (vinylidene fluoride) (PVDF) and
polystyrene (PS) both in the presence and absence of the additive, poly (vinylpyrolidone) (PVP) using dimethylacetamide
as solvent. The effects of compositions of PS and concentrations of PVP on shrinkage ratio, pure
water flux and percentage of water content of the blend ultrafiltration membranes were studied. The application of the
PVDF/PS blend membranes in separation of toxic heavy metal ions from aqueous streams was also attempted and the
results are discussed.
- Keywords: Ultrafiltration membrane, heavy metal separation.
