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.
