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%

Nowadays, hospital wastewater contains a high concentration of toxic pharmaceutical contaminants, posing significant threat to the environment, and human animal life. Cefixime (CFX) is one such contaminant that has detrimental impact on both aquatic terrestrial ecosystems. Therefore, it essential remove this compound using non-toxic environmentally friendly procedures ensure healthy drinking water. In study, low-cost eco-friendly nano adsorbent (nZVI/copper slag) was synthesized characterized FESEM, XRD, EDX, FTIR, zeta potential CFX from wastewater. The Response Surface Methodology (RSM) used evaluate effects experimental factors including dosage (2–10 g/L), pollutant (10–30 mg/L), pH (2–10), contact time (10–50 min) for efficient elimination. optimal conditions (adsorbent dosage: 7.79 g/L, concentration: 19.42 mg/L, pH: 4.59, reaction time: 36.17 resulted in 98.71% removal. adsorption isotherm kinetics data showed pseudo-second-order Langmuir models were appropriate Furthermore, demonstrated 90% elimination after up six repeated cycles regeneration reusability testing. Finally, nZVI/CS can be an effective promising solution removing

Abstract Magnetic nanoparticles can be considered a reliable tool for targeted drug delivery to cancer tissues. Based on this, in this study, the anticancer effect of iron oxide coated with glucose and conjugated Safranal (Fe 3 O 4 @Glu-Safranal NPs) liver cell line (HepG2) was investigated. Physicochemical properties were characterized using FT-IR, XRD, VSM, EDS-mapping, SEM TEM imaging, zeta potential, DLS analyses. MTT test used investigate inhibitory normal lines. Also, reactive oxygen species (ROS) level, population apoptotic cells, cycle analysis evaluated control nanoparticle-treated cells.
