Cyanide ions are very toxic because they block the iron of the respiratory enzyme and thus inhibit the oxygen transport. For humans 1 mg cyanide per kg body weight is considered lethal.
This test covers free cyanide and cyanide complexes which can be destroyed with chlorine. If interfering substances like heavy metal complexes, thiocyanate, sulphide, dyes or aromatic amines are present, a distillation according to DIN 38 405-D 13–2–2 must precede the cyanide test.
