Applications of Iodine
- Animal feed: The production of ethylenediammonium diiodide (EDDI) consumes a large fraction of available iodine. EDDI is provided to livestock as a nutritional supplement.
- Disinfectant and water treatment: Elemental iodine is used as a disinfectant in various forms. The iodine exists as the element, or as the water soluble triiodide anion I 3 – generated in situ by adding iodide to poorly water-soluble elemental iodine (the reverse chemical reaction makes some free elemental iodine available for antisepsis).
- Protection from radioactive fallout: Radioactive iodine is a potential component of nuclear fallout, and a dangerous one due to the thryroid gland’s propensity to concentrate iodine from the bloodstream.
- Radiocontrast agent: Iodine, as a heavy element, is quite radio-opaque. Organic compounds of a certain type (typically iodine-substituted benzene derivatives) are thus used in medicine as X-ray radiocontrast agents for intravenous injection.
- Other uses: Inorganic iodides find specialized uses. Hafnium, zirconium, titanium, are purified by the van Arkel Process , which involves the reversible formation of the tetraiodides of these elements.
Iodine ore crusher
Iodine is feeded into the jaw crusher for primary crushing by the vibrating feeder , then the bulk material is transfered by the elevator conveyor to grinding mill for fine grinding, and finally the finished product is out of Grinding mill and it’s fineness can reach a range of 30 -2,500 mesh.
We are a professional Iodine ore benefication equipment manufacturer and supplier, our Iodine ore crushing fleet contains: PE jaw crusher (primary crusher), JC jaw crusher (Secondary crusher), PF impact crusher , PFW impact crusher (secondary crusher), cone crusher (fineness crusher),VSI crusher (fineness crusher). We also can supply portable crusher and mobile crusher to the clients according to the demands. After the crushing process, the crushed Iodine ore will be taken to the concentrator for grinding into fine powder.
Precautions and toxicity of elemental iodine
Elemental iodine is an oxidizing irritant and direct contact with skin can cause lesions, so iodine crystals should be handled with care. Solutions with high elemental iodine concentration such as tincture of iodine and Lugol’s solution are capable of causing tissue damage if use for cleaning and antisepsis is prolonged.
Elemental iodine (I2) is poisonous if taken orally in larger amounts; 2–3 grams of it is a lethal dose for an adult human.
Iodine vapor is very irritating to the eye, to mucous membranes, and in the respiratory tract. Concentration of iodine in the air should not exceed 1 mg/m³ (eight-hour time-weighted average). When mixed with ammonia and water, elemental iodine forms nitrogen triiodide which is extremely shock sensitive and can explode unexpectedly.
