Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Heavy metals are widespread toxic environmental pollutants that can generate enormous
health and public concern. Iron (oxyhydr) oxides are ubiquitous in both natural and …

Despite substantial experimental evidence of electron transfer, atom exchange, and
mineralogical transformation during the reaction of Fe (II) aq with synthetic Fe (III) minerals …

Poorly crystalline Fe (III)(oxyhydr) oxides like ferrihydrite are abundant in soils and
sediments and are often associated with organic matter (OM) in the form of mineral-organic …

Red soil is an important soil resource, which bears substantial implication for sustainable
development of agriculture and healthy growth of economy. However, the red soil in China …

Results from enriched 57Fe isotope tracer experiments have shown that atom exchange can
occur between structural Fe in Fe (III) oxides and aqueous Fe (II) with no formation of …

Life requires a wide variety of bioessential trace elements to act as structural components
and reactive centers in metalloenzymes. These requirements differ between organisms and …

The environmental mobility and bioavailability of antimony (Sb) are strongly influenced by
sorption to Fe (III) oxide minerals, such as goethite (αFeOOH). Exposure to aqueous Fe (II) …

Aqueous Fe (II) has been shown to exchange with structural Fe (III) in goethite without any
significant phase transformation. It remains unclear, however, whether aqueous Fe (II) …

Despite substantial experimental evidence for Fe (II)–Fe (III) oxide electron transfer,
computational chemistry calculations suggest that oxidation of sorbed Fe (II) by goethite is …
