Bionic construction of iron ion-specific porous adsorbents for mitigating iron toxicity across diverse organisms

Key Points

• This research aims to develop adsorbents that specifically target iron ions to mitigate toxicity in various organisms.
• Preparation of iron-specific porous adsorbents with octahedral adsorption sites
• Testing the adsorption capacity in simulated TCM solutions
• Evaluation of selectivity for Fe3+ ions in plant solutions
• Adsorbents showed high-capacity adsorption of Fe3+ ions at 20 ppm
• Materials enriched Fe3+ ions without affecting other essential metal ion concentrations
• Demonstrated remarkable selectivity for iron ions across different plant types
