Preparation and Characterization of Low MWCO PES/SPSF Blend Ultrafiltration Membrane

Abstract:

The polyethersulfone/sulfonated polysolfone (PES/SPSF) blend ultrafiltration (UF) membranes with excellent performance were prepared by immersion phase inversion technique. The effects of degree of sulfonation (DS) of SPSF, PES/SPSF ratio, temperature of coagulation bath on the membrane porosity, pure water flux and rejection of PEG were investigated. The results show that the membrane performance with low molecular weight cut-off (MWCO) is excellent when the SPSF with 30% DS is added and the blending ratio of PES/SPSF is 4/1. The temperature of coagulation bath affects the structure of the membrane.
