摘要

由于芳香族聚酰胺反渗透膜在抗污染性以及耐氯性方面存在不足，限制了其在海水淡化等方面的应用。采用往油相中添加氧化石墨烯（GO）的二次界面聚合法改性了商业反渗透膜，评价了GO掺杂反渗透混合基质膜的分离性能和耐氯性能，并用接触角仪、Zeta电位仪、扫描电镜和原子力显微镜等仪器表征了膜的亲水性能、荷电性能以及膜表面形貌。结果表明，GO的添加提高了膜的分离性能、耐氯性能和亲水性能；当GO添加量为30 mg·L-1时，膜的通量为（77.7±0.9） L·m-2·h-1，膜的截留率为97.6%±0.5%，相比商业膜分别提高了38.4%和4.5%。当氯化强度低于4800 mg·L-1·h时，膜的水通量和盐截留率变化不明显。

Abstract

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.
