In this work, Eucommia ulmoides leaf extract (EUOLstabilized silver nanoparticles (EUOL@AgNPs) incorporated sulfonated polyether sulfone (SPES)/polyethersulfone (PES) electrospun nanofiber membranes (SP ENMs) were prepared by electrospinning, and they were studied for the removal of lead (Pb(II)) and cadmium (Cd(II)) ions from aqueous solutions. The SP ENMs with various EUOL@AgNPs loadings were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscope, thermo-gravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and contact angle (CA) measurements. The adsorption studies showed that the adsorption of Cd(II) and Pb(II) was rapid, achieved equilibrium within 40 min and 60 min, respectively and fitted with non-linear pseudo-second-order (PSO) kinetics model. For Cd(II) and Pb(II), the Freundlich model described the adsorption isotherm better than the Langmuir isotherm model. The maximum adsorption capacity for Cd(II) and Pb(II) was 625 and 370.37 mg g
−1 respectively at neutral pH. Coexisting anions of fluoride, chloride, and nitrate had a negligible influence on Cd(II) removal than the Pb(II). On the other hand, the presence of silicate and phosphate considerably affected Cd(II) and Pb(II) adsorption. The recyclability, regeneration, and reusability of the fabricated EUOL@AgNPs-SP ENMs were studied and they retained their high adsorption capacity up to five cycles. The DFT measurements revealed that SP-5 ENMs exhibited the highest adsorption selectivity for Cd(II) and the measured binding energies for Cd(II), Pb(II), are 219.35 and 206.26 kcal mol−1 , respectively. The developed ENM adsorbent may find application for the removal of heavy metals from water. [ABSTRACT FROM AUTHOR]- Published

• Novel PVDF/SnO 2 composite membrane was successfully prepared via phase inversion. • Removal of different toxic heavy metals and removal mechanisms were investigated. • Addition of SnO 2 nanomaterials had a significant impact on membrane characteristics. Global consideration has been growing recently to tackle the toxic and carcinogenic effects of heavy metal presence in water streams. In this work, novel polyvinylidene fluoride (PVDF)/tin(IV) oxide (SnO 2) ion exchange membranes were prepared via the phase inversion method and their performance and properties were analyzed. The results showed that the addition of SnO 2 nanoparticles (SnNPs) led to an improvement in the pure water flux from 25.5 ± 1.5 L/m2.h in the pristine PVDF membrane to 250.5 ± 12.5 L/m2·h in the 1.00 wt% PVDF/SnNPs membranes. This was related to the increase in the overall porosity and hydrophilicity of the membranes. Additionally, the 0.25 wt% PVDF/SnNPs membrane reported the highest tensile strength equal to 21.3 ± 0.6 MPa compared to only 14.3 ± 0.4 MPa in the pristine PVDF membrane. Lastly, the maximum removal of Pb2+, Cu2+, Zn2+, Cd2+, and Ni2+ was achieved by the 0.25 wt% PVDF/SnNPs membrane with around 93.9 ± 1.7, 92.8 ± 1.3, 82.3 ± 2.0, 70.7 ± 1.1, and 63.9 ± 1.5%, respectively, compared to 93.5 ± 1.3, 92.9 ± 1.7, 68.3 ± 2.1, 50.3 ± 1.8, and 50.3 ± 1.4% in the pristine PVDF membrane. The mechanism of removal was predicted to be a combination of ion exchange/adsorption, inner-sphere complexations and electrostatic attraction between the metal ions and the SnNPs. Such a PVDF/SnNPs membranes have great potential in the field of wastewater treatment. [ABSTRACT FROM AUTHOR]

• Composite UF membranes of polyethersulfone (PES) and α-ZrP were developed. • The hydrophilicity of PES membrane increased with the incorporation of α-ZrP. • PES/α-ZrP membranes have higher mechanical strength, porosity, & thermal stability. • The membranes efficiently removed Cd2+, Cu2+, Ni2+, Pb2+, and Zn2+ from wastewater. • Composite membranes exhibited antifouling and self-cleaning properties. This research aimed at synthesizing polyethersulfone/α-zirconium phosphate (PES/ α-ZrP) flat-sheet nanocomposite ultrafiltration (UF) membranes. The impact of α-ZrP nanoparticle (NP) addition on the morphology, functionalities, hydrophilicity, and surface charge of the membrane, among others, were investigated. Different concentrations of α-ZrP NPs (0.25, 0.50, 0.75, and 1.00 wt.%) were tested. Membranes surface morphology was investigated by Fourier-transform infrared (FT-IR), energy-dispersive X-ray spectroscopy (EDS), and scanning electron microscopy (SEM). Microscopic analyses affirmed that the α-ZrP NPs were successfully incorporated into the PES membranes. Also, the composite membranes were hydrophilic reporting increased mechanical strength, porosity, and thermal stability than the pristine PES membrane. An overall removal efficiency of 70.2 ± 1.0, 99.7 ± 0.2, 81.7 ± 1.1, 74.4 ± 1.5, and 91.5 ± 2.0 % for Cd2+, Cu2+, Ni2+, Pb2+, and Zn2+ was reported, respectively when 0.25 wt.% of α-ZrP NPs was added. The enhanced capabilities of the composite membranes in the heavy metal removal was ascribed to the increased electrostatic attraction forces with the metal ions in the solution and the surface of the PES/α-ZrP composite membrane. Lastly, the developed membranes demonstrated less fouling with self-cleaning properties which can be very beneficial in the field of industrial wastewater treatment. [ABSTRACT FROM AUTHOR]

- Abstract
In this study, commercial cellulose membranes were surface coated with alpha‑zirconium phosphate nanoparticles (α -ZrP-n) to study their impact on the overall removal efficiency of heavy metals from synthetic metal mixture wastewater solution. A total of four homogeneous solutions (0.25, 0.50, 0.75, and 1.00 wt%) of α -ZrP-n were prepared by sonicating the nanoparticles in deionized water. These solutions were used to surface coat the commercial cellulose membranes. The Scanning Electron Microscopy (SEM) along with Energy Dispersive Spectroscopy (EDS) were used to confirm the attachment of α -ZrP-n on the cellulose membrane surface. Furthermore, the structural characteristics of the α -ZrP-n modified cellulose membranes were also studied. The water contact angle results showed that all coated membranes remained super-hydrophilic. The porosity of the membranes decreased to 48% with the addition of 1.00 wt% α -ZrP-n compared to 65% for the pristine membrane. The mechanical strength has improved from 3.4 MPa for the pristine membrane to about 4 MPa for the 1.00 wt% α -ZrP-n membrane. Similarly, the thermal stability was found to be slightly enhanced as evidenced by the increase in decomposition temperature to 280 and 285 °C in the 0.75 and 1.00 wt% α -ZrP-n membranes, respectively. Furthermore, a removal efficiency of 97.0 ± 0.6, 98.0 ± 0.5, 99.5 ± 0.2, and 91.5 ± 2.0% for Cu (II), Zn (II), Ni (II), and Pb (II), respectively, was observed with the 0.50 wt% α -ZrP-n membrane. This removal was achieved at a flux of 41.85 ± 0.87 × 103 LMH. Increasing the α -ZrP-n concentration further did not show any improvement in the overall removal efficiency. However, it led to 46% flux reduction in the 1.00 wt% α -ZrP-n membrane. The mechanism of removal of the heavy metal ions was postulated to be a combination of ion exchange and electrostatic attraction of the strong negatively charged α -ZrP-n membranes and the free metal ions in the wastewater solution. Unlabelled Image • Cellulose/ α -ZrP-n ion exchange membranes were fabricated via surface coating. • Removal mechanisms of heavy metals were confirmed via membrane characterization. • Up to 97, 98, and 99% removal of Cu (II), Zn (II), and Ni (II) were achieved. • High water permeability through cellulose/ α -ZrP-n membranes was accomplished. • Cellulose/ α -ZrP-n membranes reported slight improvement in tensile strength.

[Display omitted] • Amine functionalized GO/MnO 2 nanohybrid was synthesized. • GO-MnO 2 nanohybrid was used as filler in sulfonated polyethersulfone UF membranes. • 4 wt% GO-MnO 2 membrane (SPGM4) reported 118% increase in water flux. • SPES-GO-MnO 2 composite membranes revealed high Ni2+, Cu2+, and Zn2+ rejection. • SPGM4 membrane showed excellent anti-fouling properties with ≈90% flux recovery. This study presents the synthesis of a novel graphene oxide-manganese oxide (GO-MnO 2) nanohybrid and its incorporation into sulfonated polyethersulfone (SPES) ultrafiltration (UF) membranes for wastewater treatment applications. The nanohybrid was first prepared by grafting ethylenediamine (ED) onto the edge of GO followed by direct mixing with the MnO 2 nanosheets. The composite membranes were prepared via the phase inversion method and optimized by varying the concentration of the GO-MnO 2 nanohybrid (0–6 wt%). The membranes were characterized using scanning electron microscopy, surface zeta potential, water flux, porosity, among others. The results showed that the pure water flux increased from 59.5 ± 2.5 L·m−2·h−1 in the pristine SPES membrane to 129.7 ± 4.1 L·m−2·h−1 in the SPGM4 (4 wt% GO-MnO 2). Furthermore, the heavy metal ions rejection improved from 70.1, 49.1, and 55.8% for Cu2+, Zn2+, and Ni2+ ions, respectively, in the pristine SPES membrane to 81.1, 64.0, and 67.4% in the SPGM4 membrane. Also, the composite membranes revealed improvement in the anti-fouling properties over the pristine SPES membrane. For example, the SPGM4 membrane recovered 90.5 ± 2.9% of its initial flux compared to only 72.6 ± 3.1% in the pristine membrane after 4 cycles of heavy metal filtration and simple acid cleaning steps. Overall, the addition of GO-MnO 2 nanohybrid enhanced the properties of the pristine SPES, creating new potential for such composite membranes in the wastewater treatment industry.

POLYVINYLIDENE fluoride , *HEAVY metals , *METAL ions , *SEWAGE , *SURFACE charges - Abstract
The removal of heavy metal ions from industrial wastewater is essential as they pose serious threats to human health and the environment. In this study, novel poly(vinylidene fluoride) (PVDF)-alpha-zirconium phosphate (PVDF-α-ZrP) mixed matrix membranes (MMM) were prepared via the phase inversion method. Membranes with different α-ZrP nanoparticles (NPs) loadings (0.25, 0.50, 0.75, or 1.00 wt%) were fabricated. The impacts of α-ZrP NP loading on the membrane's morphology, functionality, surface charge, and hydrophilicity were evaluated. Fourier-transform infrared and the energy-dispersive X-ray spectroscopy were performed to verify the presence of α-ZrP NPs in the fabricated membranes. The PVDF membranes became more hydrophilic after incorporating the α-ZrP NPs. The thermal and mechanical stability and porosity of the PVDF-α-ZrP MMM were higher than those of the pristine PVDF membrane. The increased hydrophilicity, pore size and porosity and reduced surface roughness of the PVDF-α-ZrP membrane led to significant flux increase and reduced fouling propensity. The PVDF-α-ZrP membrane containing 1.00 wt% α-ZrP was capable of removing 42.8% (Cd2+), 93.1% (Cu2+), 44.4% (Ni2+), 91.2% (Pb2+), and 44.2% (Zn2+) from an aqueous solution at neutral pH during filtration. • Fabrication of novel PVDF- α -ZrP mixed matrix membranes via phase inversion method. • Tunable porosity and hydrophilicity of mixed matrix membranes with α -ZrP NPs. • High water flux PVDF-α-ZrP mixed matrix membranes after incorporation of α -ZrP NP. • Removal of heavy metals from their synthetic mixture using mixed matrix membranes.
