New calcareous soil-alginate composites for efficient uptake of Fe(III), Mn(II) and As(V) from water

- A viable, green and cost-effective treatment of wastewater and water industries.
- New series of hydrogel composite microparticles as potential metal sorbents.
- The new composites are based on combination of alginates and calcareous soil.
- Effect of alginate origin on uptake efficiency was investigated for the first time.
- The composites showed efficient removal of Fe(III), Mn(II) and relatively As(V).
