Chilean saltpeter [potassium nitrate (KNOj)] has a number of impurities, including sodium and calcium iodate. Iodine is separated from the impurities and, after being treated chemically, finally produces diatomic iodine. Today, iodine is mostly recovered from sodium iodate (NalO ) and sodium periodate (NalO ) obtained from Chile and Bohvia. [Pg.255]

Hot aqueous solution of calcium hydroxide and iodine react in the presence of chlorine to form calcium iodate, Ca(I03)2. [Pg.168]

Iodine is widely distributed in nature, found in rocks, soils and underground brines. An important mineral is lautarite, which is anhydrous calcium iodate found in nitrate deposits in Chde. The element also occurs in brown seaweeds, in seawater, and in many natural gas wells. Its concentration in the earth s crust is an estimated 0.5 mg/kg and in seawater 0.06 mg/L. [Pg.397]

IV.21 IODATES, IO3 Solubility The iodates of the alkali metals are soluble in water those of the other metals are sparingly soluble and, in general, less soluble than the corresponding chlorates and bromates. Some solubilities in g -1 at 20° are lead iodate 0 03 (25°), silver iodate 0-06, barium iodate O 22, calcium iodate 3-7, potassium iodate 81-3, and sodium iodate 90 0. Iodic acid is a crystalline solid, and has a solubility of 2,330 g t 1 at 20°. [Pg.340]

Iodine occurs as iodide in brines and in the form of sodium and calcium iodates. Also, various forms of marine life concentrate iodine. Production of iodine involves either oxidizing I- or reducing iodates to I" followed by oxidation to the elemental state. Exact methods vary considerably depending on the raw materials. A commonly used oxidation reaction, and one suited to laboratory use when necessary, is oxidation of I" in acid solution with Mn02 (also used for preparation of Cl2 and Br2 from X ). [Pg.551]
