Arsenate sulfate

Arsenate sulfate refers to a class of inorganic compounds containing both arsenate (AsO43−) and sulfate (SO42−) anions, often found in mineral forms or as secondary products in geochemical and industrial processes. These compounds are typically associated with arsenic-rich environments, such as mine tailings, hydrothermal systems, and hypersaline lakes, where arsenic and sulfur coexist. Arsenate sulfates are of interest in mineralogy, environmental chemistry, and biogeochemistry due to their role in arsenic mobility, toxicity, and microbial interactions. A notable example is beudantite.
