Abstract: Iron in +6 oxidation state, called ferrate(VI), is an emerging environmentally-friendly sustainable green material, which can play an important role in treatment of water and wastewater. The theme of the presentation will be to elucidate multi-modal actions of ferrate(VI) in water sustainability by demonstrating disinfection, coagulation, and oxidation. Examples of disinfection include inactivation of chlorine resistant microorganisms and coagulation of toxic metals such as arsenic and lead. Oxidative transformation of a wide range of pharmaceuticals in water will be presented. Recent research on “Activated Ferrate” to oxidize recalcitrant different micropollutants in water will be discussed. A wide range of micropollutants in water can be degraded by “Activated Ferrate” with high efficiency, in seconds, which would otherwise take several minutes or hours by ferrate(VI) without activation. The oxidative transformation mechanisms of micropollutants by “Activated Ferrate” involving highly reactive iron intermediates (i.e., FeV and FeIV) will be delineated. Overall, iron-based cost-effective material can improve water reuse.
