Implication

Batch sorption tests showed 70% Fe3+ removal in aqueous solutions, suggesting glycine's potential for efficient iron remediation.

Key Points

  • SG-Gly-Na⁺ achieved 70% Fe³⁺ removal efficiency, showing significant improvement over unmodified silica gel.
  • XANES analysis indicated Fe³⁺ remains in the +3 oxidation state upon sorption, confirming iron stability.
  • Characterization through ATR-FTIR and SEM validated the structural integrity and thermal stability of the silica gel.
  • The glycine moiety does not reduce Fe(III) within the matrix, underscoring its selective capture of iron ions.
