Environmental damage from serious nuclear accidents should be urgently restored, which needs the removal of radioactive species. Radioactive iodine isotopes are particularly problematic for human health because they are released in large amounts and retain radioactivity for a substantial time. Herein, we prepare platinum-coated iron nanoparticles (Fe@Pt) as a highly selective and reusable adsorbent for iodine species, i.e., iodide (I- ), iodine (I2 ), and methyl iodide (CH3 I). Fe@Pt selectively separates iodine species from seawater and groundwater with a removal efficiency ≥ 99...
