ClarkeIodine is a trace element and an indispensable nutrient for the human body. The human body is 60 micrograms a day.
Iodine is one of the important raw materials for thyroid hormone synthesis. If iodine is deficient, the level of thyroid stimulating hormone will rise, resulting in thyroid hyperplasia and hypertrophy and goiter. At the same time, insufficient thyroid hormone will also affect the growth, development and metabolic performance of the body, which is a single minor disease or intellectual disorder.
Iodine is an essential trace element of human body and one of halogen elements. Iodine has the weakest chemical activity among halogen elements, but it can still be combined directly with most elements and widely exists in nature in the form of compounds. Iodine is slightly soluble in water and hydrolyzed to produce stable hypoiodic acid, which can make the brownish yellow aqueous solution acidic.
Iodine is easily soluble in organic solvents such as ethanol, ether and glycerol. Iodine is blue with starch, which can be used for qualitative and quantitative detection. Seaweed is rich in iodine and is the main raw material for extracting pure iodine. Iodine also comes from seaweed in industry. It is mainly used in medicine, fuel, photosensitive materials and chemical reagents.
