Summary

Iron nanoparticles efficiently remove nickel ions from water by acting as both a sorbent and a reductant. This dual functionality offers a superior method for nickel sequestration compared to traditional inorganic sorbents.

  • High-resolution X-ray photoelectron spectroscopy (HR-XPS) for surface analysis.

    • Main Results:

    • Iron nanoparticles demonstrated a high nickel removal capacity (0.13 g Ni/g Fe).
    • The removal capacity exceeded that of the best inorganic sorbents by over 100%.
    • HR-XPS confirmed a core-shell structure with sorbent and reductant properties.

    Conclusions:

    • Iron nanoparticles effectively sequester Ni(II) through a dual sorption-reduction mechanism.
    • The unique properties of iron nanoparticles provide advanced solutions for metal ion separation and transformation.
    • This technology holds promise for environmental remediation of heavy metal contaminants.
