High efficiency removal of dissolved As(III) using iron nanoparticle-embedded macroporous polymer composites
Abstract
Novel nanocomposite materials where iron nanoparticles are embedded into the walls of a macroporous polymer were produced and their efficiency for the removal of As(III) from aqueous media was studied. Nanocomposite gels containing ?-Fe2O3 and Fe3O4 nanoparticles were prepared by cryopolymerisation resulting in a monolithic structure with large interconnected pores up to 100 ?m in diameter and possessing a high permeability (ca. 3 × 10?3 m s?1). The nanocomposite devices showed excellent capability for the removal of trace concentrations of As(III) from solution, with a total capacity of up to 3 mg As/g of nanoparticles. The leaching of iron was minimal and the device could operate in a pH range 3–9 without diminishing removal efficiency. The effect of competing ions such as SO42? and PO43? was negligible. The macroporous composites can be easily configured into a variety of shapes and structures and the polymer matrix can be selected from a variety of monomers, offering high potential as flexible metal cation remediation devices.
