“…Therefore, advanced membrane materials have attracted a large part of research in membrane technology for wastewater treatment. In general, filtration membranes are usually prepared from a polymer, due to their high competitiveness in energy‐saving and pollution‐free performance, 7,8 such as polysulfone, polyvinylidene fluoride, cellulose acetate, polyethersulfone (PES), polyacrylonitrile, polyetherimide and polyvinyl chloride 9 …”

BACKGROUNDIn this work, polyphenylsulfone /polyethersulfone (PPSU /PES) composite membrane was successfully prepared using the phase inversion method in the presence of polyethylene glycol (PEG) as the hydrophilic additive. The effect of concentration of PEG (0, 2, 4, and 6 wt.%), were investigated by SEM, FTIR, TGA, and contact angle analysis.RESULTSThe obtained results confirmed that the morphology and hydrophilicity of theporous membrane varied with the addition of PES as reinforcing agent and the PEG concentration as porogen. SEM results confirmed that the membranes obtained have a high permeability with a finger‐shaped structure and that the size and density of the pores increase with the increase in the incorporated PEG. The contact angle was decreased and the porosity of the PPPn blend membranes was increased from 16.06 with the neat PPSU membrane to 385. 3 Lh−1m−2 bar−1 with the PPP6 membrane. A strong interaction between the composition of (PPSU, PES and PEG) was revealed by FTIR and TGA analysis.CONCLUSIONThe filtration results showed PPP2 is the better formulation of the dope suspension in the range ultrafiltration membranes in terms of flux (179.3 Lh−1m−2 bar−1) and BSA retention (94%).The application of polyelectrolyte enhanced ultrafiltration (PEUF) using polyethylenimine (PEI) for the removal of cobalt ions allowed obtaining high removal rates (92.5%). The optimal performances have been obtained at pH ≥ 4, 4 bars of transmembrane pressure and 1200 ppm of PEI.This article is protected by copyright. All rights reserved.
