Abstract

Novel polyphenylsulfone (PPSU)/nano tin oxide (SnO2) mixed matrix hollow fiber membranes (HFMs) were fabricated by dry-wet spinning via phase separation method. In the current research, reported the contrast between neat PPSU membrane and nanocomposite membranes (PPSU/SnO2), to determine the toxic reactive dyesnamely,reactiveblack-5(RB-5)andreactiveorange-16(RO-16)removalabilityfromtheaqueousmedia. Scanningelectronmicroscopy(SEM)wasusedtoobservetheHFMscross-sectionalmorphologicalchangesand surfaceroughnessparametersofmembraneswereanalyzedusingatomicforcemicroscopy(AFM).Thesurface wettabilityabilityofHFMswasexaminedwithacontactangle,wateruptake,andporositymeasurements.The cross-flow filter unit was engaged to quantify the water permeability, anti-fouling ability as well as the dye rejection ability of fabricated membranes. With increasing the SnO2 NPs wt% in PPSU polymer matrix the membrane performance was enhanced continuously, it became evident that the incorporated SnO2 NPs plays mainroleinmembraneperformance.Added,water-solublepoly(vinylpyrrolidone)(PVP)canalsoimpactthe poremorphologyinmembranes.Attheend,PS-3membraneexhibitedlowercontactangle(63.70),higherwater uptake (74.8%), porosity (84.1%), pure water flux 362.9L/m2h, and high potential for dyes rejection application,ofabout>94%forRB-5,and>73%forRO-16dye,respectively.Fromthepreliminaryresults,itcanbe statedthattheusageofSnO2 NPsinmembranetechnologybecomeeffectivetowardswastewatertreatment.
