Overview

Laboratory study demonstrates effective lead removal by magnetic iron oxide-chitosan composites in aqueous solutions, highlighting their potential as reusable adsorbents for water remediation.

Key Points

  • Fabricate magnetic Fe3O4/chitosan nanocomposites at different ratios and evaluate their adsorption performance for removing Pb(II) from aqueous solutions.
  • Synthesized Fe3O4/chitosan nanocomposites using co-precipitation and chitosan coating, followed by structural and magnetic characterization using XRD, FTIR, SEM-EDX, TEM, and VSM.
  • Performed batch adsorption tests to evaluate the influence of pH, contact time, adsorbent dosage, initial Pb(II) concentration, and temperature on adsorption performance.
  • The Fe3O4/chitosan (1:1) composite demonstrated the highest adsorption capacity of 44.31 mg/g at pH 5, reaching equilibrium after 120 minutes while retaining magnetic recoverability.
  • Adsorption kinetics conformed to the pseudo-second-order model, equilibrium data aligned with the Langmuir isotherm, and thermodynamic analysis confirmed a spontaneous, endothermic process (ΔH° = +16.64 kJ/mol).
