A novel approach for arsenic adsorbents regeneration using MgO

- Low-cost and efficient regeneration of FeOOH arsenic adsorbents by MgO.
- Continuous flow NaOH recirculation system for on-site application in adsorption beds.
- As(V) is adsorbed onto MgO in the form of monodentate inner sphere complexes.
- Environmentally safe and profitable handling of saturated MgO in cement.
