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 …

Advanced treatment of refractory industrial wastewater is still a challenge. Coking
wastewater is one of coal chemical wastewater, which contains various refractory organic …

Mixed-valent iron [Fe (II)-Fe (III)] minerals such as magnetite and green rust have received a
significant amount of attention over recent decades, especially in the environmental …

In this study, we construct a surface Fenton system with hydroxylamine (NH2OH), goethite (α-
FeOOH), and H2O2 (α-FeOOH–HA/H2O2) to degrade various organic pollutants including …

Iron biominerals are formed by a broad host of organisms, in which they serve various
functions. For example, iron oxides formed by organisms serve for strengthening of tissues1 …

Using the isotope specificity of 57Fe Mössbauer spectroscopy, we report spectroscopic
observations of Fe (II) reacted with oxide surfaces under conditions typical of natural …

Iron oxides may undergo structural transformations when entering an anoxic environment.
These transformations were investigated using the isotopic exchange between aqueous Fe …

Arsenic (As) is a potentially toxic element (PTE) that causes adverse effects on human
health through contamination of soil and groundwater worldwide. Biochar has captured …

The reaction of aqueous Fe (II) with Fe (III) oxides is a complex process, comprising sorption,
electron transfer, and in some cases, reductive dissolution and transformation to secondary …

Arsenic contamination in groundwater is a critical issue and one that raises great concern
around the world as the cause of many negative health impacts on the human body …
