Modified composites based on mesostructured iron oxyhydroxide and synthetic minerals: A potential material for the treatment of various toxic heavy metals and its toxicity

- Meso-iron-oxyhydroxide was found to be efficient for anion heavy metal adsorption.
- The composite bead can simultaneously remove the cations and anions of heavy metals.
- Powdered form had stronger cytotoxicity than did the granular form.
- Adsorbent recovery is facilitated by granulation process of powder-type.
