ABSTRACT:
In a method for the remediation of inorganic arsenic species, a solution of inorganic arsenic is passed over zero valent iron under abiotic and anaerobic conditions, thereby removing the inorganic arsenic species and forming arsenic-metal co-precipitates. The metal is preferably in the form of iron filings, and is provided together with sand.
