Area of Science:

  • Materials Science
  • Environmental Science
  • Chemistry

Background:

  • Fluoride contamination in aqueous media poses significant health risks.
  • Developing efficient and stable adsorbents for fluoride removal is crucial for water purification.
  • Metal-organic frameworks (MOFs) show promise due to their tunable structures and high surface areas.

Purpose of the Study:

  • To prepare and characterize composite nanofiber membranes (CNMs) using UiO-66 and UiO-66-NH2 Zr-metal-organic frameworks (MOFs).
  • To evaluate the performance of these CNMs in adsorptive fluoride removal from aqueous solutions.
  • To investigate the key parameters influencing fluoride adsorption and assess the adsorbent's stability and reusability.

Main Methods:

  • Synthesis of CNMs incorporating UiO-66 and UiO-66-NH2 MOFs.
  • Characterization using X-ray diffraction (XRD), FE-SEM, BET, and FTIR.
  • Adsorption experiments to determine optimal conditions (dose, pH, time, concentration).
  • Evaluation of adsorption kinetics, isotherms, hydrothermal stability, and regeneration cycles.

Main Results:

  • UiO-66-NH2 CNMs demonstrated high fluoride removal efficiency (95%) under optimal conditions (20 mg L-1, pH 8, 60 min).
  • UiO-66-NH2 CNMs exhibited a higher maximum adsorption capacity (95 mg g-1) compared to UiO-66 CNMs (75 mg g-1).
  • The adsorbent showed good hydrothermal stability and retained its structure after fluoride adsorption, with effective regeneration over three cycles.

Conclusions:

  • UiO-66-NH2 derived CNMs are highly effective and stable adsorbents for fluoride removal from aqueous media.
  • Electrostatic interactions and hydrogen bonding play key roles in the fluoride adsorption mechanism.
  • The developed CNMs show significant potential for practical applications in water treatment due to their high capacity and reusability.
