The fate of cyanides in soil is strongly influenced
by the formation of Fe cyanides, which can interact with
organic and inorganic colloids and precipitate as stable
compounds. Scarce information is available on the capacity
of humic acids to interact with cyano-complexes and thus
affect the leaching and prevent the risk of contamination of
watertable. Here we show that interaction between humic
acids (HAs) and ferricyanide complex led to a formation
of ferricyanide-humo micelles, and that the interaction did
not imply changes in the original structure of ferricyanide
complex
