Investigation of acetone as co-solvent on performance PES nanofiltration membrane

Polyethersulfone (PES)-based on mixed matrix nanofiltration membrane was developed by amalgamationwith Partially reduced acetone nanocomposite. The effect of acetone fillings on the morphology and performance of theprepared membranes was examined by scanning electron microscopy (SEM) and water contact angle analysis. Theblended membranes showed improved water permeability and fouling resistance likened to the simple PES. When thecontent of acetone was 100 wt.%, the water flux touched a maximum value (10.5 kg/m2 h) nearly twice of that of thesimple PES membrane (3.5 kg/m2 h). Fouling confrontation of the membranes studied by stupid serum albuminsolution filtration presented that 10 wt.% acetone membrane had the best antifouling property. Nanofiltrationperformance of the prepared membranes was assessed by rejection of three organic dyes with different molecularmasses.
