Short description: Research by staff at the University of Brighton has led to the development of a novel, low energy, natural-analogue-based, electrokinetic system called FIRS (Ferric Iron Remediation and Stabilisation). The FIRS system applies a low magnitude direct electric potential between two or more sacrificial iron-rich electrodes placed at opposing sides of a mass of contaminated soil or sediment. The electric potential generates a strong Eh-pH gradient between the two electrodes, promotes anodic dissolution, Fe0 and Fe2+(aq) migration, and forces the precipitation of ferric iron oxyhydroxides, hematite, goethite, magnetite and zero valent iron, at near neutral pH values at the interface of the anodic and cathodic domains.
