The present work deals with the fabrication of novel poly(vinylidene fluoride) (PVDF)/Multi-wall Carbon Nanotubes (MWCNT)/Polypyrrole (PPy) ultrafiltration membrane by phase inversion technique for the removal of crude oil from refinery wastewater. In situ polymerization of pyrrole with different concentrations of MWCNT ranging from 0.025 wt.% to 0.3 wt.% in PVDF prepared solutions. Measurement of permeability, porosity, contact angle, tensile strength, zeta potential, rejection studies and morphological characterization by scanning electron microscopy (SEM) were conducted. The results showed that membrane with (0.05% MWCNT) concentration had the highest permeability flux (850 LMH/bar), about 17 folds improvement of permeability compared to pristine PVDF membrane. Moreover, membrane rejection of crude oil reached about 99.9%. The excellent performance of this nanocomposite membrane suggests that novel PVDF modification with polypyrrole had a considerable effect on permeability with high potential for use in the treatment of oily wastewater in the refinery industry.
本工作通过相转化技术制备了新型聚偏氟乙烯（PVDF）/多壁碳纳米管（MWCNT）/聚吡咯（PPy）超滤膜，用于去除炼油废水中的原油。在PVDF制备溶液中，将吡咯与浓度范围为0.025 wt.%至0.3 wt.%的不同MWCNT进行原位聚合。进行了渗透率、孔隙率、接触角、拉伸强度、zeta电位的测量、截留研究以及通过扫描电子显微镜（SEM）进行的形态表征。结果表明，浓度为（0.05% MWCNT）的膜具有最高的渗透通量（850 LMH/bar），与原始PVDF膜相比，渗透率提高了约17倍。此外，原油的膜截留率达到约99.9%。这种纳米复合膜的优异性能表明，用聚吡咯对新型PVDF进行改性对渗透率有显著影响，在炼油行业含油废水处理中具有很高的应用潜力。
