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

Herein, we prepared iron-specific porous adsorbents with six oxygen-formed deformable octahedral adsorption sites. The resulting solids exhibited remarkable selectivity and high-capacity adsorption of Fe3+ ions in simulated TCM solutions (20 ppm). Notably, the materials selectively enrich Fe3+ ions from various plants with high capacity while maintaining the concentrations of other essential metal ions unchanged.
