Iron (Fe) and water Water Treatment and Purifiion

Iron is essential for nitrogen binding and nitrate reduction, and it may be a limiting factor for phytoplankton growth. Solubility in salt water is extremely low. The iron cycle means reduction of tertiary iron by organic ligands (a process that is photo alysed in surface waters), and oxidation of binary iron.
