Influence of copper oxide nanomaterials in a poly(ether sulfone) membrane for improved humic acid and oil–water separation

Abstract: In this study, self‐synthesized copper(I) oxide (Cu2O) nanoparticles were incorporated in poly(ether sulfone) (PES) mixed‐matrix membranes (MMMs) through the phase‐inversion method. A cubic arrangement and crystallite size of 28 nm was identified by transmission electron microscopy and X‐ray diffraction (XRD) for the as‐synthesized Cu2O particles. The pristine PES membrane had a higher contact angle value of 88.50°, which was significantly reduced up to 50.10° for 1.5 wt % PES/Cu2O MMMs. Moreover, XRD analysis… Show more

“…The higher the Ag‐CNT content in the PSf nanocomposite membrane was, the higher the BSA rejection (≥90%) was. This was obviously because of lower flux values and the improved hydrophilicity of the composite membranes …”

“…The FRR of the bare‐PSf membrane was 42%; this indicated serious membrane fouling issues during BSA filtration, whereas the nanocomposite membrane fabricated with a 0.2% Ag‐CNT loading exhibited the highest flux recovery of 79%. Because the bare‐PSf membrane was less hydrophilic than the PSf/Ag‐CNT nanocomposite membranes, the foulants could easily adsorb on the membrane surface or inside the membrane pores and could not be washed by simple water flushing . The addition of the Ag‐CNTs induced hydrophilicity characteristics in the membranes and, thus, recovered the permeability of the membranes.…”

“…Hydrophilic modification by incorporating inorganic nanoparticles is considered as an effective approach to improve the antifouling performance of polymer membrane . Several inorganic nanoparticles, such as TiO 2 , SiO 2 , one‐dimensional‐PANI/TiO 2 , copper(I) oxide, phosphorylated TiO 2 ‐SiO 2 particles, and sulfated Y‐doped zirconia particles, have already been introduced into PVDF membranes to improve the hydrophilicity for oily wastewater treatment.…”

“…However, as typical inorganic additives, HNTs are prone to aggregate in membrane matrix or leach out to the coagulation bath during the phase inversion process. Therefore, it is difficult for HNTs to disperse uniformly in membrane matrix, which needs to be overcome urgently . One of the effective methods is to graft chemicals which have good compatibility with organic materials onto the hydrophilic additives, thus enhancing the dispersibility of the hydrophilic additives and developing specific interactions between additives and polymer matrix .…”

“…The as-synthesized composites membranes displayed enhanced permeability, improved porosity, better hydrophilicity, excellent antifouling ability, and water uptake compared to the polysulfone membranes. Through the phase-inversion route, self-synthesized Cu 2 O nanoparticle was introduced into the poly(ether sulfone) mixed-matrix membrane [73]. About 1.5 wt% of the nanocomposite showed an improved water permeability of 66.72 × 10 −9 m s/k/Pa.…”
