“…The 1/ n values implied that the DCA preferred to adsorb to the surface of TDNMs. Some previous studies have also demonstrated the adsorption of organic chemicals to LDHs [ 32 ] or graphene-based materials [ 18 ]. It was also found that the Freundlich adsorption coefficient ( K F ) decreased in the order Mg-Al-LDH > Zn-Al-LDH > GNP.…”

The assessment and prediction of the toxicity of engineered nanomaterials (NMs) present in mixtures is a challenging research issue. Herein, the toxicity of three advanced two-dimensional nanomaterials (TDNMs), in combination with an organic chemical (3,4-dichloroaniline, DCA) to two freshwater microalgae (Scenedesmus obliquus and Chlorella pyrenoidosa), was assessed and predicted not only from classical mixture theory but also from structure-activity relationships. The TDNMs included two layered double hydroxides (Mg-Al-LDH and Zn-Al-LDH) and a graphene nanoplatelet (GNP). The toxicity of DCA varied with the type and concentration of TDNMs, as well as the species. The combination of DCA and TDNMs exhibited additive, antagonistic, and synergistic effects. There is a linear relationship between the different levels (10, 50, and 90%) of effect concentrations and a Freundlich adsorption coefficient (KF) calculated by isotherm models and adsorption energy (Ea) obtained in molecular simulations, respectively. The prediction model incorporating both parameters KF and Ea had a higher predictive power for the combined toxicity than the classical mixture model. Our findings provide new insights for the development of strategies aimed at evaluating the ecotoxicological risk of NMs towards combined pollution situations.

Graphene, a two-dimensional hexagonal honeycomb carbon structure, is widely used in membrane technologies thanks to its unique optical, electrical, mechanical, thermal, chemical and photoelectric properties. The light weight, mechanical strength, anti-bacterial effect, and pollution-adsorption properties of graphene membranes are valuable in water treatment studies. Incorporation of nanoparticles like carbon nanotubes (CNTs) and metal oxide into the graphene filtering nanocomposite membrane structure can provide an improved photocatalysis process in a water treatment system. With the rapid development of graphene nanocomposites and graphene nanocomposite membrane-based acoustically supported filtering systems, including CNTs and visible-light active metal oxide photocatalyst, it is necessary to develop the researches of sustainable and environmentally friendly applications that can lead to new and groundbreaking water treatment systems. In this review, characteristic properties of graphene and graphene nanocomposites are examined, various methods for the synthesis and dispersion processes of graphene, CNTs, metal oxide and polymer nanocomposites and membrane fabrication and characterization techniques are discussed in details with using literature reports and our laboratory experimental results. Recent membrane developments in water treatment applications and graphene-based membranes are reviewed, and the current challenges and future prospects of membrane technology are discussed.

“…[ 14 ] Graphene oxide (GO) is a single‐atomic‐layered of carbon atoms with a 2D planar structure, which possesses oxygen groups such as hydroxyl (–OH), epoxide (C–O–C), and carboxyl (COOH) performing their negative surface charge and hydrophilic properties, capable of adsorbing several heavy metal ions and dyes [ 15 ] through different mechanisms, including the π–π bonding, H‐bonding, anionic/cationic attraction and ion exchange of organic compounds or heavy metals. [ 16 ] In addition, GO demonstrated promising antibacterial properties associated with the contact of the bacterial outer membrane with their oxygenated groups, capable of generating oxidative stress. [ 17 ] As a result, GO represents an effective multifunctional additive for successful NF membrane fabrication.…”

This work explored the combined antibacterial and selective dye adsorption properties of graphene oxide (GO) incorporated into nanostructured polyethersulfone (PES) membranes. For this purpose, GO synthesis was performed by the Hummers method and characterized by Fourier transform infrared, X‐ray diffraction, Raman spectroscopy, and scanning electron microscopy (SEM) micrographs, using a graphite source as a reference. The dye adsorption capacity of GO was evaluated, obtaining a retention of ca. 66% with methylene blue (MB) and ca. 72% with methyl orange, higher than activated charcoal. In addition, the antibacterial properties of GO were evaluated against Staphylococcus aureus and Pseudomonas aeruginosa, with complete bacterial inhibition after 2 h of contact. GO was successfully incorporated into electrospun PES fibers to fabricate hybrid PES membranes, with a PES film (phase inversion) as substrate and an electrospun surface coating with PES/GO (at 1 wt%) fibers, corroborated by SEM micrographs. As a result, the hybrid PES membrane demonstrates an AA ca. 85% after 2 h of contact with both microorganisms and an improvement in colorant retention after two and four cycles of filtration, respectively. In addition, the adsorption isotherm and kinetics demonstrate the enhancement of the PES/GO membrane's performance in contact with MB solutions. Our results suggest that the GO incorporation into nanostructured hybrid membranes improves the fabrication of multifunctional NF membranes, with a potential application in wastewater treatment. Highlights Combined antibacterial/dye adsorption capacity of PES/GO membranes was found. Nanostructured membrane by PES and PES/GO fibers decorated was obtained. PES/GO demonstrates antibacterial features against Staphylococcus aureus and Pseudomonas aeruginosa. Enhanced dye adsorption capacity of PES/GO membrane was performed with MB. PES/GO membranes show properties for successful NF membrane development.
