The membranes were prepared by using solution casting method. The membranes were prepared by casting a solution of polymer in the mixture of 1-butanol and 1-propanol (4:1). The membrane was prepared by dissolving 10 wt% of the polymer in solvent mixture at elevated temperature. Solutions were casted on a heated glass plate at a thickness of 1000 |im. Films were dried in nitrogen atmosphere for 3 days. The membrane was completely dried under reduced pressure for a few days. The final thickness of the membranes was about 100 |im (Yildirim et al., 2008).
