ABSTRACT:
The specification discloses a method for the treatment of particulate materials such as soils and sludges containing arsenic compounds which comprises contacting the material with a source of iron (III) ions and a source of magnesium (II) ions to stabilize the material against leaching of arsenic. A preferred source of iron (III) ions is iron (III) sulfate and a preferred source of magnesium (II) ions is magnesium oxide.
