Realizing the potential of metallic iron for the mitigation of toxics: flee or adapt?

Abstract Metallic iron (Fe 0 ) has been increasingly used to remove toxics from water over the past three decades. However, idea that metallic is not an environmental reducing agent vigorously refuted. Researchers presenting their findings in a scientific journal have accept burden of proving argument any validity. This 30-year-lasting discussion within Fe remediation community alien electro-chemists, as it century-old knowledge. Nevertheless, peer-reviewed literature on “remediation using ” seems be dominated by evaluators thinking agent. communication challenges view donates electron dissolved species. The sole goal reconcile proven efficient technology with its roots and enable design better systems.
