Iodine | Ise Chemicals Corporation

Manufacturing process. Groundwater that contains dissolved natural gas in aquifers is called brine. Although the element of brine is similar to that of seawater, brine is a suitable source in the production of iodine because it contains a large amount of iodine, roughly 0.1 g/L, as opposed to seawater, which contains only 0.0001 g/L or less.

How chemistry shaped societies: the case of the Atacama Desert in Chile

From 2001, SQM, the Chilean producer, changed the production process in order to reduce the content of perchlorate to below 0.1 g kg −1, and now < 0.05 g kg −1 . Perchlorates must be eliminated from nitrates used as fertilizers, since they can interfere with the assimilation of iodine by the thyroid gland [ 39 ] in humans.
