Commercial polyvinylalcohol/polyacrylonitrile hybrid membranes crosslinked separately by B1, B2, B3, and S1 were tested for their abilities to recover tetrafloropropanol (TFP) by pervaporation (PV). The structure and of the membranes were also determined by scanning electron microscope. A preliminary PV experiment was conducted at 60 °C with the water content in the feed solution fixed at 5 wt%. Both the separation factor and pervaporation separation index (PSI) were highest with the S1 membrane. Analytical results reveal that the separator factor is approximately 4-369 kg m-2 h-1, total flux 0.13-4.73 kg m-2 h-1, and the PSI value 12.54-90.54 kg m-2 h-1 in the temperature range of 50-70 °C and feed concentration of TFP range of 72.5-99 wt%. The separation factor increases and total flux decreases as the water concentration decreases and operational temperature decreases.
