Arsenic Reduction. Chemical Formula: As, HAsO4, AsO2. Present as: elemental metalloid, anion. Overview. Products. Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid.

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 of both As(V) and iron (hydr)oxides can thus have a pronounced influence on As partitioning. However, it is presently unclear whether As desorption under anaerobic …
