Abstract：

In this study, two different modified graphene oxides were derived, namely polyether amine modified graphene oxide (PEA-GO) and bisphenol A modified graphene oxide (BPA-GO). The modified GO were filled into PEBA to prepare mixed matrix membranes, and their pervaporation performance for phenol/water separation were investigated. IR and XPS characterization proved that the modifications are successful. XRD results indicated that the interlayer spacing of BPA-GO increased significantly. The modified GO showed improved adsorption for phenol. The adsorption capacity of BPA-GO reached 147.8 mg/g. After filling modified GO, the separation factor and permeation flux of the pervaporation membrane have been improved. The mixed matrix membrane BPA-GO-PEBA had the better pervaporation performance than PEA-GO-PEBA membrane. It had the permeation flux of 308 g/(m2·h)and the separation factor of 21.1 at the temperature of 55℃. Due to the fact that BPA-GO had better phenol adsorption property and increased d-spacing, the flux and separation factor of BPA-GO-PEBA membrane increased by 50.2% and 88.4% respectively, compared with the mixed matrix membrane filling unmodified GO. According to the pervaporation experiments data and Arrhenius equation, the activation energy of phenol permeation was 81.0 kJ/mol, which was higher than that of PEBA blank membrane and the mixed matrix membrane with unmodified GO. Therefore, with the temperature increasing, the separation factor and permeation flux of the mixed matrix membrane BPA-GO-PEBA increased markedly.
