Potassium iodate may be used to protect against accumulation of radioactive iodine in the thyroid by saturating the body with a stable source of iodine prior to exposure. [9] Approved by the World Health Organization for radiation protection, potassium iodate (KIO 3 ) is an alternative to potassium iodide (KI) , which has poor shelf life in hot ...
[citation needed] Seaweed-fertilizer also helps in breaking down clays. [ citation needed ] Fucus is used by Irish people as a biofertilizer on a large scale. [ citation needed ] In tropical countries, the bottom mud from dried-up ponds which contain abundant blue-green algae is regularly used as biofertilizer in fields.
Iodine-131 (131 I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. [3] It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production.
Iodine rarely occurs naturally in mineral form, so it comprises a very small portion of rocks by mass. [2] Sedimentary rocks have higher concentrations of iodine compared to metamorphic and igneous rocks. [4] Due to the low concentration of iodine in rocks, weathering is a minor flux of iodine to soils and the freshwater hydrosphere. [1]
USP Tincture of Iodine is defined in the U.S. National Formulary (NF) as containing in each 100 mL, 1.8 to 2.2 grams of elemental iodine, and 2.1 to 2.6 grams of sodium iodide. Alcohol is 50 mL, and the balance is purified water. This "2% free iodine" solution has 0.08 mol/L of I 2, which provides about 1 mg of free iodine per 0.05 mL drop. The ...
Percentage of share of households consuming iodized salt. Edible salt can be iodised by spraying it with a potassium iodate or potassium iodide solution. 57 grams of potassium iodate, costing about US$1.15 (in 2006), is required to iodise a ton (2,000 pounds) of salt. [1]
Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.
Fertilizers are applied to crops both as solids and as liquid. About 90% of fertilizers are applied as solids. The most widely used solid inorganic fertilizers are urea, diammonium phosphate and potassium chloride. [53] Solid fertilizer is typically granulated or powdered. Often solids are available as prills, a solid globule. Liquid ...
