摘要：
The present study deals with the synthesis of polyethersulfone (PES)-based membrane using a biopolymer sericin and polyvinylpyrrolidone (PVP) by phase inversion process. The synthesized membranes were characterized for hydrophilicity, pure water permeability (PWP), membrane stability, and surface functional group analysis. The synthesized membranes were used to study the effective removal of cadmium ions using poly(diallyldimethylammoniumchloride) and polyethyleneimine (PEI) by polyelectrolyte-enhanced ultrafiltration. PVP-sericin-incorporated PES membrane resulted in the highest average pore radius (22nm) and PWP (34.11Lm(-2)h(-1)bar(-1)). It also showed that higher antifouling resistance of 10 folds than neat PES membrane retained the higher flux rate. Overall, PES/sericin/PVP membrane has better characteristics, and maximum percentage of cadmium removal was obtained when added with PEI ligand.
