Modified polyethersulfone membranes for micellar enhanced ultrafiltration of chromium
Separation performances of micellar enhanced ultrafiltration process in Cr(III) and Cr(VI) removal has been evaluated. The neat as well as sulfonated and aminated derivatives of polyethersulfone were tested as the material for membrane preparation while hexadecylpyridine chloride and sodium dodecyl sulfate served as surfactant. It was shown that modified membranes can better reject both forms o...
متن کاملPreparation and Performance Studies on Polyethersulfone Ultrafiltration Membranes Modified with Gelatin for Treatment of Tannery and Distillery Wastewater
In this study polyethersulfone ultrafiltration membrane were prepared with the modifier gelatin at 0, 5, 10, 15 and 20 wt % using DMF as solvent by phase inversion process. Morphologies and characteristics of the membranes were investigated through the methods of SEM, XRD, contact angle measurements. The performance of the modified membrane for the treatment of leather and distillery wastewater...
متن کاملHeterogeneous Functionalization of Polyethersulfone: A New Approach for pH-Responsive Microfiltration Membranes with Enhanced Antifouling Properties
In this work, 2,2’-azo-bis-butyronitrile (AIBN) was exploited as an initiator for the successful bulk heterogeneous functionalization of polyethersulfone (PES) using polymethacrylic acid (PMAA), for the first time. To this end, pH-responsive and exceptionally low fouling membranes of extremely low grafting degrees with low adhesion and high rejection of protein were fabricated. An added advanta...
متن کاملEnzymatic Modification of Polyethersulfone Membranes
Enzymatic modification of polyethersulfone (PES) membranes has been found not only feasible, but also an environmentally attractive way to vary surface properties systematically. In this paper, we summarize the effect of modification layers on protein adsorption and bacterial adhesion on PES membranes and surfaces. The enzyme laccase was used to covalently bind (poly)phenolic acids to the membr...
متن کاملPreparation, Characterization and Application Studies of PVDF- PS Ultrafiltration Membranes
Polyvinyledenefluoride–polystyrene (PVDF/PS) blend ultrafiltration membranes were prepared using phase inversion technique. Casting solutions were prepared with different compositions of polyvinylidene fluoride (PVDF) and polystyrene (PS) both in the presence and absence of the additive, polyvinylpyrolidone (PVP) using dimethylacetamide as solvent. The effects of compositions of PS and concentr...
