Preparation of PVA Nanofiltration Membrane with Good Solvent Resistance

Abstract:

Polyvinylalcohol (PVA) with good solvent resistance was used in preparation of nanofiltration membrane. The preparation parameter such as PVA concentration, cross-linking agent concentration and reaction time are studied in detail. When the composite membrane was prepared under optimized conditions and tested at 0.4 MPa and 20 °C, the flux of the NF membrane was about 15 L/m²h and the Na₂SO₄ rejection of it was about 53.3%.
