Implication

Synthesizes Fe(III)-Ion Imprinted Polymers and evaluates their effectiveness in removing iron from complex samples, suggesting improved pollutant separation.

Key Points

  • The aim is to develop selective sorbents for iron removal using Fe(III)-Ion Imprinted Polymers.
  • Synthesis of Fe(IIPs) using Alizarin Red-S and 2-Vinylpyridine.
  • Bulk polymerization with Trimethylolpropane trimethacrylate as a crosslinker.
  • Characterization by FTIR, SEM, and EDX.
  • Evaluation of effects of contact time, pH, and initial concentration.
  • Fe-IIPs reached maximum adsorption capacity of 134.224 mg/g at pH 5.
  • Adsorption equilibrium achieved within 30 minutes.
  • Adsorption data fit the Langmuir model and pseudo-second order kinetics.
  • Selectivity coefficient for Fe(III) exceeded unity, indicating effective imprinting.
