Use of iron(VI) and iron(V) in water and wastewater treatment.
Water Sci Technol. 2004; 49(4):69-74.WS

Abstract

Fe(VI) (Fe(VI)O4(2-)) and Fe(V) (Fe(V)O4(3-)) have high oxidizing power, selectivity, and upon decomposition produce a non-toxic by-product, Fe(III), which makes them potential oxidants in water and wastewater treatment. Rates of oxidation increase with a decrease in pH and are related to protonation of Fe(VI)O4(2-) and Fe(V)O4(3-). Oxidation of sulfur- and nitrogen-containing pollutants by Fe(VI) can be accomplished in seconds to minutes with formation of non-hazardous products. Fe(VI) can easily oxidize the amino acid components of microcystins and is a suitable disinfectant for detoxifying toxins in water. The oxidation of pollutants and amino acids with Fe(V) is 3-5 orders of magnitude faster than with Fe(VI). The use of ionizing radiation and photocatalytic techniques in the presence of Fe(VI) results in Fe(V) formation and may have synergistic effects on the oxidation of pollutants and removal of toxins in water and wastewater. This paper summarizes the results of multi-functional properties of Fe(VI) and Fe(V) to treat water and wastewater.
