Degradation of perfluorooctanoic acid using zero-valent iron coated by carboxymethyl-β-cyclodextrin polymer

Key Points

• This research investigates the effectiveness of zero-valent iron coated with carboxymethyl-β-cyclodextrin in degrading perfluorooctanoic acid (PFOA).
• Evaluated the reduction of PFOA using nZVI coated with carboxymethyl-β-cyclodextrin polymer (nFe-CMBCD).
• Measured PFOA degradation rates under controlled experimental conditions.
• Assessed the influence of different concentrations on degradation efficiency.
• Achieved up to 98% reduction of PFOA at a concentration of 0.2 mg/L.
• Demonstrated a strong reduction capability of the nFe-CMBCD composite for environmental remediation.
