Innovative cross-linked electrospun PVA/MOF nanocomposites for removal of cefixime antibiotic

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 2, 2025

In this study, we synthesized two nanocomposites, cross-linked PVA/HKUST and PVA/ZIF-67, by integrating metal–organic frameworks (MOFs) into electrospun polyvinyl alcohol (PVA). Several characterization techniques including FTIR, XRD, ICP, SEM, TGA, UV–Vis, zeta potential, N2 adsorption–desorption were employed. The adsorption performance of the composites for cefixime (CFX) removal was assessed under varying conditions such as MOF content, contact time, pH, initial CFX concentration, temperature. ZIF-67 HKUST contribute to high efficiency providing a porous structure with surface area, facilitating interactions molecules, enhancing overall stability composite material in process. Langmuir isotherm model revealed maximum capacity 282.5 mg/g 211.4 PVA/ZIF-67. Notably, rapidly removed within 50 min, demonstrating potential these nanofibers wastewater treatment. However, after six cycles, efficiencies declined from 88 74% 85 59%

(1) Background: Safety problems associated with aflatoxin B1 (AFB1) contamination have always been a major threat to human health. Removing AFB1 through adsorption is considered an attractive remediation technique. (2) Methods: To produce adsorbent high efficiency, magnetic reduced graphene oxide composite (Fe3O4@rGO) was synthesized using one-step hydrothermal fabrication. Then, the characterized series of techniques, such as SEM, TEM, XRD, FT-IR, VSM, and nitrogen adsorption–desorption analysis. Finally, effects this nanocomposite on nutritional components treated foods, vegetable oil peanut milk, were also examined. (3) Results: The optimal synthesis conditions for Fe3O4@rGO determined be 200 °C 6 h. temperature significantly affected properties prepared material due its effect layered structure loading Fe3O4 nanoparticles. results various characterizations illustrated that surface had two-dimensional nanostructure many folds nanoparticles distributed uniformly material. Moreover, isotherm, kinetic, thermodynamic analyses indicated by conformed Langmuir model, maximum capacity 82.64 mg·g−1; rapid efficient occurred mainly chemical via spontaneous endothermic process. When applied treat minimized loss nutrients thus preserved food quality. (4) Conclusions: above findings reveal promising adsorbent, Fe3O4@rGO, favorable potential safety applications.
