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 …

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 …

An overview of different chemical complexes studied by X-ray magnetic circular dichroism
(XMCD) is presented. We intend to show to the chemistry community the possibilities of this …

The origin of dissolved arsenic in the Ganges Delta has puzzled researchers ever since the
report of widespread arsenic poisoning two decades ago. Today, microbially mediated …

Ion exchange (IX) is considered by US EPA as one of the best available technologies for
removing arsenic from drinking water. However, typical IX processes will generate large …

Groundwater contamination by arsenic in Vietnam poses a serious health threat to millions
of people. In the larger Hanoi area, elevated arsenic levels are present in both, the …

X-Treme is a soft X-ray beamline recently built in the Swiss Light Source at the Paul Scherrer
Institut in collaboration with École Polytechnique Fédérale de Lausanne. The beamline is …

Arsenic (As) in soils and sediments is commonly mobilized when anoxic conditions promote
microbial iron (Fe) and As reduction. Recent laboratory studies and field observations have …

The main arsenic mitigation measures in Bangladesh, well-switching and deep tube wells,
have reduced As exposure, but water treatment is important where As-free water is not …

The fate and transport of arsenic is regulated, in part, by its strong affinity for iron (hydr)
oxides. A transition from aerobic to anaerobic conditions resulting in concomitant reduction …
