Iodine Crystal

What is Iodine ?

Iodine is primarily obtained as a by-product with nitrate minerals that are associated with caliche deposits in places such as the Atacama Desert of Chile. It is present in seawater, which contains about 0.05 ppm iodine, meaning that there are approximately 35 million metric tons of iodine in the world’s oceans, but extraction is impractical at these low concentrations. Iodine was first isolated from seaweed, and dried seaweeds, (particularly those of the Liminaria family) contain as much as 0.45 per cent. iodine. Prior to 1959
