Abstract
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.
