The incorporation of nano-materials in thin film composite (TFC) membrane has been explored in order to improve permeability/selectivity and to enhance anti-fouling properties in many water treatment processes. In this study, graphene oxide (GO) was embedded into the semi-aromatic polyamide active layer of a TFC membrane via interfacial polymerization (IP) reaction between the piperazine (PIP) and trimesoyl chloride (TMC) monomers. The properties of TFC membranes were thoroughly characterized using FTIR, FE-SEM, AFM, and water contact angle measurements. The permeation and separation performance of these membranes were also examined. The in-house fabricated PA/GO TFC membranes exhibited much higher flux (12.78 +/- 0.36 L/m(2).h.bar) than that of the pristine PA TFC membranes (8.94 +/- 0.42 L/m(2).h.bar) with a slightly increased salt rejection. Furthermore, the rejection of three target PPCPs compounds, i.e., paracetamol, norfloxacin and sulfamethoxazole was investigated using these TFC membranes with different GO loadings. The addition of GO offered a significant improvement in PPCPs rejection as a result of favorable change in membrane hydrophilicity, surface morphology and surface charge. This study offers a facile and effective route to fabricate high performance semi-aromatic PA TFC membranes incorporated with functional nano-materials.
