The antifouling properties of the membranes were studied ‎during filtration of bovine serum albumin (BSA) solutions and the governing fouling mechanisms ‎of the membranes were also investigated using the Hermia model. Fourier Transform Infrared ‎Spectroscopy (FTIR) and Thermal gravimetric analysis (TGA) confirmed that ND was ‎successfully functionalized by PEG. CA/ND-PEG nanocomposite membranes have higher ‎hydrophilicity, porosity, water uptake, mechanical strength and a lower amount of adsorbed ‎protein than pure CA and CA/ND membranes. Besides, the antifouling performance of the ‎CA/ND-PEG (0.5 wt.%) nanocomposite membrane also witnessed considerable improvement, in ‎comparison with that of pure CA and CA/ND (0.5 wt.%) membranes. The obtained results ‎showed that the best fit to experimental data for all membranes (pure and nanocomposite ‎membranes) corresponds to the cake layer formation model.‎ UR - https://www.jwent.net/article_34595.html L1 - https://www.jwent.net/article_34595_30489dedb97985b1b9582b2a972ee8f0.pdf ER -
