Iron (Fe) and waterLenntech
The iron cycle means reduction of tertiary iron by organic ligands (a process that is photo catalysed in surface waters) and oxidation of binary iron. Iron forms chelation complexes that often play an important role in nature such as haemoglobin a red colouring agent in blood that binds and releases oxygen in breathing processes.
