Dissolution behavior of iron cyanide (Prussian blue) in contaminated soils

The solubility of iron cyanide complexes [Fe(CN) 6 3- and Fe(CN) 6 4- ] in soils was studied to elucidate the possible hazards posed by soils contaminated with iron cyanide. Earlier work had indicated that these complexes probably precipitate as a form of Prussian blue, a mineral containing Fe(CN) 6 4- and iron
