摘要
由哌嗪(PIP)和均苯三甲酰氯(TMC)界面聚合制备的聚酰胺纳滤膜的通量较低和抗污染性能较差,本文通过在聚酰胺纳滤膜表面上接枝两种氨基化改性的氧化石墨烯(GO),制备高通量、耐污染的改性聚酰胺复合纳滤膜,并通过傅里叶红外光谱(ATR-FTIR spectra)、X射线光电子能谱(XPS)、扫描电子显微镜(SEM)和静态水接触角等对改性聚酰胺纳滤膜进行了表征和分析.考察了改性聚酰胺膜的通量、截留率和耐污染性能,研究结果表明,GO的加入能够有效地提高聚酰胺纳滤膜的水通量和抗污染性等性能.
The flux and fouling resistance of polyamide nanofiltration membranes prepared by PIP and TMC are poor. In this paper, polyamide nanofiltration membrane with high flux and fouling resistance were prepared by surface grafting of two kinds of amino modified graphene oxide. The modified polyamide nanofiltration membrane were characterized by Fourier infrared spectroscopy (ATR-FTIR spectra), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and static water contact angle. The performance of the modified membrane was investigated by measuring the water flux and recovery, and salt rejection. Results indicate that grafted graphene oxide can effectively increase the water flux and fouling resistance properties of the polyamide nanofiltration membrane.
