Fe/Ti co-pillared clay for enhanced arsenite removal and photo oxidation under UV irradiation

- An iron and titanium co-pillared montmorillonite (Fe-Ti/MMT) was synthesized for arsenite removal.
- Variety of characterization results indicated that Fe and Ti species were pillared in MMT.
- A possible mechanism of arsenite adsorption/oxidation with UV light was established.
- The participation of Fe component can promote the process of photocatalytic oxidation in Fe-Ti/MMT + As(III) system.
- Fe-Ti/MMT can function as both photocatalyst and adsorbent for arsenite removal.
