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

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 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%
