Chromium (III) Removal by Epoxy-Cross-Linked Polyethersulfone Ultrafiltration Membrane

This study attempts to correlate the changes in membrane morphology with the separation efficiency of the polyethersulfone/epoxy resin (pes/er) blend membranes. intermolecular interactions between the components in pes/er blend membranes were established by atr-ftir and the morphological study by field emission scanning electron microscopy (fesem) has confirmed the significant changes of pores connectivity between the sub-layers of membrane. pes/er blend membrane with 10% of er revealed highest rejection of cr(iii) ions at 85% without jeopardizing the permeate flux (12.17 l/m2h). from the results, it could be concluded that the pes/er blend membrane has the great potential in the removal of chromium ions from an aqueous waste.
