In this study, a novel MgFe2O4-Schiff base-chitosan nanocomposite was synthesized using straightforward crosslinking method. The synthesis involved integrating MgFe2O4 nanoparticles with modified chitosan through Schiff base formed by the reaction between terephthalaldehyde and aminopyrazine. A comprehensive characterization performed, including X-ray diffraction analysis, which verified crystalline structure successful incorporation of MgFe2O into chitosan-Schiff matrix. Scanning electron microscopy revealed distinct surface morphology, characterized rough, non-uniform alignment resulting from strong interactions Additionally, energy-dispersive analysis elemental composition nanocomposite, revealing peaks corresponding to carbon, nitrogen, oxygen, magnesium, iron. exhibited outstanding performance as nanoadsorbent for efficient removal Pb(II) ions aqueous media electrostatic attraction complexation mechanisms, achieving maximum adsorption capacity 290.7 mg g-1. process determined be spontaneous, endothermic, chemically driven, aligning well Langmuir isotherm model pseudo-second-order kinetics. optimal conditions were pH 5.5, contact time 100 min, temperature 328 K. Furthermore, demonstrated excellent recyclability, retaining over 94.8% its initial efficiency after five consecutive adsorption-desorption cycles. This study highlights nanocomposite's potential an eco-friendly, cost-effective, highly material practical applications in water treatment, addressing urgent need sustainable solutions heavy metal contamination.

Abstract Elimination of perfluorooctanoic acid (PFOA), a persistent pollutant that is toxic to human and ecosystem health, important. In this study, three adsorbents, C-101, W-101, NW-101, were evaluated. W-101 was modified by diamine ethyl modification enhance the number PFOA adsorption sites. The results showed (42.7 mg g −1 ) had better capacity than C-101 (12.3 ), NW-101 (698.4 best. Langmuir model correctly described isotherms adsorption, pseudo-second-order kinetic fitted process. exhibited an excellent efficiency, as it reached equilibrium within 7 min, also revealed higher reusability due stable structure amine-grafted structure; therefore, proved very efficient in removal. new method used bark poplar trees prepare MIL-101(Cr) adsorbents with surface areas 3341, 2767, 2374 m 2 for respectively. This cost-effective, eco-friendly utilizes renewable raw materials, minimizes environmental impact, represents significant advance removal thermal material research.
