Product Details

Lodine CAS#7553 - 56 - 2

Lodine is found naturally in seaweed, and is considered and generally recognized as safe substance by the US Food and Drug Administration (FDA). Iodine is a required element by many species, including humans. It has been recognized as preventative against goiter since 1819, and is used in iodized salt for this purpose. Iodine is also used as a dough oxidizer in commercial bread making. Iodine is generally extracted from natural and oil field brines by means of oxidation of iodide with chlorine, then removal from solution with an airstream. Iodine is reabsorbed in solution and reduces to hidrotic acid with sulfur dioxide. The solution is then chlorinated to precipitate free iodine, and is further purified by treatment with concentrated sulfuric acid. Iodine is the heaviest essential element for most life, with tungsten being used by some bacteria.
