This work examines the adsorption of Cu(II) ions utilizing an Fe₃O₄@anthranilic acid-chitosan nanocomposite as an effective adsorbent. The nanocomposite was produced and analyzed by SEM, EDX, XRD, and FTIR to verify its shape, composition, crystalline structure, and functional groups. The adsorption tests showed that the material could hold a maximum of 341.29 mg of Cu(II) ions per gram and remove 90% of them at a pH of 6, indicating it has a strong ability to absorb these ions. With an average particle size of 108.2 nm, the nanosorbent demonstrated a high surface contact and affinity for Cu(II) ions. The adsorption process was shown to follow a pseudo-second-order model, meaning that the main step in the process was chemical bonding, as indicated by the kinetic analysis (R2 = 0.999). Tests using real water samples from a dam, river, and pond showed that the adsorbent effectively removed Cu(II) ions, proving its effectiveness. The results demonstrate that the Fe₃O₄@anthranilic acid-chitosan nanocomposite has enormous potential as a tool for cleaning up polluted water and other environments.
