In recent years, nanomaterials have gained special attention for removing contaminants from wastewater. Nanoparticles (NPs), such as carbon-based materials and metal oxides, exhibit exceptional adsorption capacity antimicrobial properties wastewater treatment. Their unique properties, including reactivity, high surface area, tunable functionalities, make them highly effective adsorbents. They can remove organics, inorganics, pharmaceuticals, medicine, dyes by mechanisms. this review, the effectiveness of different types NPs, carbon nanotubes (CNTs), graphene-based nanoparticles (GNPs), quantum dots (CQDs), nanofibers (CNFs), nanospheres (CNSs), copper oxide (CuO), zinc (ZnO), iron (Fe2O3), titanium (TiO2), silver (Ag2O), in removal has been comprehensively evaluated. addition, their synthesis methods, physical, chemical, biological, described. Based on findings, CNPs 75 to 90% pollutants within two hours, while MONPs 60% 99% dye 150 min, except NPs. For future studies, integration NPs into existing treatment systems development novel are recommended. Hence, potential is promising, but challenges related environmental impact toxicity must be considered.

Removal of Heavy Metal Ions on Lead Ion‐Imprinted Modified Polyurethane Wet‐Spun Fibers

Polymers for Advanced Technologies, Год журнала: 2025, Номер 36(1)

Опубликована: Янв. 1, 2025

ABSTRACT The molecular imprinted polymers are prepared by imprinting technique with specific selectivity in target substances. To prepare high performance and lead ion adsorbent, hence, chitosan was used to blend polyurethane; the modified fiber a matrix for initiating graft polymerization of acrylic acid on surface. Lead fibers were lead‐ion as template epichlorohydrin crosslinking agent. influence rate adsorption properties materials lead‐ions analyzed. result suggests that maximum is 59.10%; hydrophilicity stability grafted membranes significantly improved. Furthermore, saturated capacity reaches under 20°C nearly neutral. relative selection coefficients cupric cadmium 2.72 6.06, respectively. This indicates show potential adsorbent removing heavy metal ions.
