Usage: Iodine is used in the manufacture of manyiodine compounds; in photographic materi als; as an antiseptic, disinfectant, and germi cide; and as a reagent in analytical chemistry.It occurs in traces in seawater and in igneousrocks.
It is usually purified by vacuum sublimation. Preliminary purifications include grinding with 25% by weight of KI, blending with 10% BaO and subliming, subliming with CaO, grinding to a powder and treating with successive portions of H2O to remove dissolved salts, then drying, and recrystallising from *benzene. Barrer and Wasilewski [Trans Faraday Soc 57 1140 1961] dissolved I2 in concentrated KI and distilled it, then steam distilled it three times and washed it with distilled H2O. Organic material is removed by sublimation in a current of O2 over platinum at about 700o, the iodine being finally sublimed under vacuum. HARMFUL VAPOURS.
