This study aimed to analyze the adsorption behavior of Fe(III) ions from aqueous solutions onto naturally derived chitosan beads functionalized with esterified vanillin–cinnamate (1). The produced material was characterized by FTIR, XRD, and SEM–EDX analyses. Kinetic and equilibrium studies were employed to evaluate the effects of solution pH, contact time, and adsorbent dosage in a batch system. The optimal situations for Fe(III) adsorption were found to be a solution pH of 6, an adsorbent dosage of 20 mg, and a contact time of 60 min. The adsorption capacity and desorption efficiency based on Langmuir were 135.85 mg/g and 83.17% for Fe(III) ions. Chitosan beads functionalized with ester vanillin–cinnamate (1) demonstrated effective performance as a bioadsorbent for the removal of Fe(III) ions by aqueous solutions. This study underscores the potential of chitosan-based materials as efficient adsorbents for wastewater treatment applications
