Interactions of arsenic with synthesized pyrite were investigated using macroscopic (solution phase experiments) and microscopic (X-ray photoelectron spectroscopic investigation) approaches. Arsenic removal by pyrite was strongly dependent on pH and arsenic species. Both arsenite (As(III)) and arsenate (As(V)) had a strong affinity for the pyrite surface under acidic conditions, but As(III) was more effectively removed than As(V). A BET isotherm equation provided the best fit to arsenic removal… CONTINUE READING
