Iron molecules have strong affinity with inorganic arsenic species. Thus, iron is a very good adsorbent for the removal of arsenic from the wastewater. Arsenic species can be removed by iron and it can act as adsorbent and co-precipitant or can cause pollutant immobilization (Mondal et al. 2013 ).Web

The mechanism of As(III) adsorption on biogenic schwertmannite involves ligand exchanges between arsenic species and surface hydroxyl group and sulfate. In addition, experiments show that As(III)-sorbed biogenic schwertmannite aged in deionized water at 25°C exhibits no mineralogy phase changes even after ageing at pH 6.0 and 8.5 for 90d.Web
