摘要：

Poly(vinyl alcohol)/graphene composite membranes were prepared and used in pervaporation to separate benzene-isooctane mixtures. The prepared membranes were characterized by SEM, XRD, FTIR, TGA, degree of swelling and contact angle to examine properties of composite membranes. The performance of the poly(vinyl alcohol)/graphene membranes was studied for the feed composition range 15-60 wt% benzene at different temperatures (45-60 degrees C). The optimized membrane separation performance was reported in terms of flux (1.28 g m(-2) h(-1)), selectivity (48.66) and pervaporation separation index (61.21) at 60 degrees C. The maximum percentage of benzene in permeate was 89.57% at 15 wt% benzene in feed solution.
