چکیده:

Porous membranes were prepared by non-solvent induced phase inversion from miscible blends of polyvinylchloride and thermoplastic polyurethane. Pure water flux measurement showed that addition of TPU to PVC results in reduction of the operating pressure of the membranes compared to pure PVC membranes with best properties obtainable at a blend composition of 75:25 (PVC:TPU). The performance of blend membranes was examined in the removal of Coomassie Brilliant Blue G-250 dye with a molecular weight of 854.02 g/mol from its aqueous solutions. Results indicated that the prepared membranes are even capable of 100% dye rejection with potential application as nanofiltration membranes
