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

Arsenic is a non-essential element that poses risks in many environments, including soil,
groundwater, and surface water. Insights into the environmental biogeochemistry of As can …

Aqueous arsenic speciation, or the chemical forms in which arsenic exists in water, is a
challenging, interesting, and complicated aspect of environmental arsenic geochemistry …

Refining the occurrence characteristics of tailings hazardous materials at source is of great
importance for pollution management and ecological reclamation. However, the release and …

Jarosite can be an important scavenger for arsenic (As) and antimony (Sb) in acid mine
drainage (AMD) and acid sulfate soil (ASS) environments. When subjected to reducing …

Jarosite, beudantite and alunite are members of the alunite supergroup. Minerals like those
have been detected in different environments on Earth. These jarosite-type compounds are …

Jarosite coprecipitation with hazardous oxyanions can attenuate the concentrations of these
elements in acid mine drainage. However, jarosite can be easily transformed to goethite with …

Arsenic (As) is a problematic pollutant that can cause cancer and other chronic diseases
due to its potential toxicity. Iron (oxyhydr) oxides can readily sorb As and play important roles …

Wastes derived from the exploitation of stibnite ore deposits were studied to determine their
mineralogical, chemical, and environmental characteristics and establish the Sb distribution …

We applied spectroscopy, microscopy, diffraction, and aqueous chemistry methods to
investigate the persistence of metals in water and sediments from the Animas River 13 days …
