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 …

Acid mine drainage (AMD) is often accompanied with elevated concentrations of arsenic, in
the forms of arsenite, As (III), and/or arsenate, As (V), due to the high affinity of arsenic for …

Removal of arsenic (As) from water supplies is needed to reduce As exposure through
drinking water and food consumption in many regions of the world. Magnetite nanoparticles …

Uranium (U) is a ubiquitous element in the Earth's crust at~ 2 ppm. In anoxic environments,
soluble hexavalent uranium (U (VI)) is reduced and immobilized. The underlying reduction …

Iron-biochar is an efficient adsorbent for contaminants, whereas the role of prepared
temperature on removal of antimony (Sb) is unacquainted. In this study, the iron-biochar …

Arsenic (As) is a toxic element, and elevated levels of geogenic As in drinking water pose a
threat to the health of several hundred million people worldwide. In this study, we used …

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 …

More than 100 million individuals worldwide are exposed to arsenic-contaminated water,
making the investigation of arsenic mobility in aquatic systems of utmost importance. Iron …

In this study, magnetite–maghemite nanoparticles were used to treat arsenic-contaminated
water. X-ray photoelectron spectroscopy (XPS) studies showed the presence of arsenic on …

To reduce the adverse effects of arsenic on humans, various technologies are used to
remove arsenic from groundwater, most relying on As adsorption on Fe-(oxyhydr) oxides …
