Dehydration of ethyl acetate aqueous solution by pervaporation using PVA/PAN hollow fiber composite membrane

► PVA/PAN hollow fiber composite membrane was prepared. ► Tartaric acid (Tac) and maleic anhydride (Mac) were used as cross-linking agents. ► Effects of Tac and Mac on the PV performances of PVA/PAN membrane were studied. ► PVA/PAN composite membrane had good dehydration performance for EAc/H2O solution.
