“…The increased onset degradation temperature of PGT composites and residue (%) was correlated to the so-called thermal stability (Table S3). It may be due to the proper distribution of the thermally stable GO-Mt filler in the PU matrix . So, the formation of a thermally stable electrospun composite membrane was confirmed.…”

Multifunctional materials for industrial wastewater treatment are in high demand due to the contamination of microand nanoplastics (MNPs) and dyes. Herein, we demonstrate a polyurethane-based (PU) electrospun composite membrane for MNP separation and selective methylene blue (MB) adsorption. The optimized 20 wt % graphene oxide-montmorillonite (GO-Mt)-loaded nanofibrous composite membrane (20-PGT) exhibited its superhydrophilicity with a water contact angle of 0°and high water flux. It displayed a maximum pressure-driven water flow of 8163 L m −2 h −1 and a gravity-driven water flux of 793 L m −2 h −1 . Three model MNPs, such as acrylonitrile butadiene styrene (ABS), polystyrene (PS), and poly(methyl methacrylate) (PMMA) with various sizes, have been demonstrated. The adsorptive separation and size-exclusive interception mechanisms were observed for nanoplastics (NPs) and microplastics (MPs), respectively. Cake formation, intermediate blocking, and standard blocking mechanisms were followed during the filtration of ABS MPs, PMMA NPs, and PS NPs, respectively. Additionally, the composite membrane exhibited selective MB adsorption from the mixture of dyes, with a maximum adsorption capacity of 417 mg g −1 . Langmuir adsorption isotherm and pseudo-second-order kinetics define the adsorption isotherm and adsorption kinetics, respectively. The fabricated, robust fibrous composite membrane opens a wider door for the removal of MNPs and MB from contaminated water.

“…Time consumption has been considered a determinant in choosing the wastewater treatment method by private sectors. [ 114 ] To reach dye removal of more than 90%, laccase‐immobilized into glycidyl methacrylate‐functionalized polyacrylamide‐alginate cryogel requires 300 min to complete a single cycle. [ 97 ] Another example, aniline‐based dye reduction of 91% could be achieved by 72‐h batch process.…”

Global threat from emerging contaminants to human health has pushed researchers to develop pollutant removal technologies including those based on biocatalytic degradation. Laccase, a multicopper enzyme, is reported for its applicability in treating wastewater and industrial effluent by catalyzing reduction of O 2 to H 2 O in the presence of substrates (phenolic or non-phenolic compounds). Scientific papers have discussed the ability of this enzyme to breakdown hazardous contaminants ranging from azo dyes, antibiotics, and up to hormones. Nonetheless, the cost production of this enzyme is high, hence the importance of the immobilization into solid supports. Polymers are considered suitable for the immobilization because they are easy for modification and have adjustable characteristics. This review discusses the immobilization of laccase into polymers via various techniques (adsorption, cross-linking, covalent binding, encapsulation, and entrapment) and its implications on the pollutant removal performance. In addition, bibliometric analysis is performed and summarized the advantages and disadvantages of each immobilization technique.

“…A polyether sulfone modified with a graphene oxide membrane was used to treat tannery industry wastewater with a high rejection efficiency of chromium (˃99%) [ 14 ]. Other uses are the removal of antibiotics with a pillararene-MXene membrane [ 15 ] and the removal of dyes (77–100%), phenols (40–100%), and heavy metals (66–100%) [ 16 ]. For this reason, the present work focuses on the development and characterization of a hybrid membrane of acetate cellulose particles of ZnO.…”

Water polluted by discarded heavy metals such as lead is creating a global pollution problem. In this work, adsorption of Pb(II) was realized in batch studies by a hybrid membrane of cellulose acetate with ZnO particles. First, ZnO particles were prepared by precipitation and immobilized on the membrane. The hybrid membrane was elaborated by interfacial polymerization. The structure and surface were characterized based on Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). Batch experiments were carried out under different conditions where the number of particles of ZnO present in the membrane and the pH of the aqueous solution were varied. The Langmuir and Freundlich isotherm models were evaluated in the best adsorption conditions. Data fitted well with a Langmuir model with a maximum adsorption capacity of 15.55 mg·g−1, which was similar for this type of materials. Thermodynamic parameters such as Gibbs free energy, enthalpy, and entropy showed that the process was spontaneous and favorable. The hybrid membrane was evaluated in simulated wastewater of the battery industry with a superior efficiency of up to 97%; without the medium, it did not generate interference. These results suggest that Pb(II) removal by hybrid membrane is possible.
