  • Title: Arsenic(V) removal from underground water by magnetic nanoparticles synthesized from waste red mud.
    Author: Akin I, Arslan G, Tor A, Ersoz M, Cengeloglu Y.
    Journal: J Hazard Mater; 2012 Oct 15; 235-236():62-8. PubMed ID: 22846216.
    Abstract:
    In this study waste red mud (bauxite residue) sample obtained from Seydişehir (Konya, Turkey) was evaluated for the synthesis of Fe(3)O(4) nanoparticles (NPs) in ammonia solution that can be used to remove As(V) from both synthetic and natural underground water samples. The synthesized Fe(3)O(4)-NPs were characterized by using TEM, VSM, XRD, SAXS, TGA and FT-IR spectroscopy. The Fe(3)O(4)-NPs assumed a near-sphere shape with an average size of 9 nm. The results showed that synthesized Fe(3)O(4)-NPs from waste red mud have satisfactory magnetic properties and As(V) sorption capacity, especially at low equilibrium arsenate concentrations.
