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