The pervaporation behaviours of aqueous ethanol mixtures through the poly (ethylene oxide) (PEO)/chitosan (CS) blend membrane have been investigated.The results show that both CS and PBO/CS membranes preferentially permeate ethanol at lower ethanol concentration in feed, and the selectivity of chitosan membrane toward alcohol can be greatly improved by introducing water-soluble polymer PBO into chitosan.
