In this article, we provide a critical review on the occurrence, formation, structure and stability
of schwertmannite–an enigmatic Fe (III) oxyhydroxy-sulfate mineral that is of widespread …

Acid sulfate soils (ASS) contain substantial quantities of iron sulfide minerals or the oxidation
reaction products of these sulfidic minerals. Transformation of iron (Fe) and sulfur (S) …

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 …

The Fe (II)-catalysed transformation of synthetic schwertmannite, ferrihydrite, jarosite and
lepidocrocite to more stable, crystalline Fe (III) oxyhydroxides is prevented by high, natural …

In floodplain soils, As may be released during flooding-induced soil anoxia, with the degree
of mobilization being affected by microbial redox processes such as the reduction of As (V) …

Iron minerals in soils and sediments play important roles in many biogeochemical processes
and therefore influence the cycling of major and trace elements and the fate of pollutants in …

This study describes the sorption of As (V) and As (III) to schwertmannite as a function of pH
and arsenic loading. In general, sorption of As (V) was greatest at low pH, whereas high pH …

Schwertmannite affects the mobility of antimony (Sb) in acid mine drainage, yet the Sb
sorption mechanism remains elusive. In this study, the molecular-level mechanism and the …

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 …

This study explores interactions between As and Fe (III) minerals, predominantly
schwertmannite and jarosite, in acid mine drainage (AMD) via observations at a former mine …
