Abstract :

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