Metal ion removal from the aqueous feed using PVDF/PS blend ultrafiltration membranes
Year: 2010
Type: article
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.
