摘要：

The aromatic polyamide reverse osmosis membrane is poor in anti-fouling performance and chlorine resistance, which is limiting its application in some fields. The commercial reverse osmosis membrane was modified by the secondary interface polymerization method of adding graphene oxide (GO) to the oil phase. The separation performance and chlorine resistance of GO-doped reverse osmosis mixed matrix membranes were evaluated. The properties of the membranes were characterized by water contact angle, Zeta potential,scanning electron microscopy (SEM) and atomic force microscopy(AFM). The results show that the addition of GO increases the hydrophilicity, separation performance and chlorine resistance of the membrane. With 30 mg•L-1GO content, the flux and rejection rate of the membrane reach peak values of (77.7±0.9) L•m-2 •h-1 and 97.6%±0.5%, increasing 38.4% and 4.5% respectively. When the chlorination intensity is less than 4800 mg•L-1•h, the changes of water flux and salt rejection rate of the membrane are not obvious. © All Right Reserved.
