Structure, properties, spectra, suppliers and links for: Potassium iodide, 7681-11-0. Potassium iodide is a chemical compound, medication, and dietary supplement. Such radiation doses will not occur far away from an accident site. At maximal doses, and sometimes at much lower doses, side effects of iodide used for medical reasons, in doses of 1000 times the normal nutritional need, may include: acne, loss of appetite, or upset stomach (especially during the first several days, as the body adjusts to the medication). [52] Because the volumes of KI and water are approximately additive, the resulting SSKI solution will contain about 1.00 gram (1000 mg) KI per milliliter (mL) of solution. [46][47], As of 2020, potassium iodide tablets are made available free of charge for all residents in all pharmacies throughout the country. Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. The use of KI...was credited with permissible iodine content in 97% of the evacuees tested. Highest to lowest - 1) Diamond - 3550°C 2) Potassium Chloride - 775°C 3) Ice - 0°C (Note that these are all at normal atmospheric pressure) <3 Melting point of Potassium is 63.25°C. A useful application is in the preparation of aryl iodides from arenediazonium salts. For reasons noted above, therapeutic drops of SSKI, or 130 mg tablets of KI as used for nuclear fission accidents, are not used as nutritional supplements, since an SSKI drop or nuclear-emergency tablet provides 300 to 700 times more iodine than the daily adult nutritional requirement. Microiodide. 0 0. [7681-11-0] These compounds contain iodine, but not in the iodide form. However, adolescents approaching adult size (i.e., >70 kg [154 lbs]) should receive the full adult dose (130 mg) for maximal block of thyroid radioiodine uptake. Lugol's solution (TN) Iodine-potassium iodide complex. ... M.

Due to its high potassium content, SSKI is extremely bitter, and if possible it is administered in a sugar cube or small ball of bread. The melting point of a substance depends on pressure and is … 7790-42-3. Potassium iodide can block absorption of radioactive iodine by the thyroid gland through flooding the thyroid with non-radioactive iodine and preventing intake of radioactive molecules, thereby protecting the thyroid from cancer causing radiation. How long will the footprints on the moon last? [citation needed], There is reason for caution with prescribing the ingestion of high doses of potassium iodide and iodate, as their unnecessary use can cause conditions such as the Jod-Basedow phenomena, trigger and/or worsen hyperthyroidism and hypothyroidism, and then cause temporary or even permanent thyroid conditions. Melting Point Of Potassium Iodide. Today, nearly half (44.8%) the survivors of Nagasaki studied have identifiable thyroid disease, with an editorial in The Journal of the American Medical Association reporting "it is remarkable that a biological effect from a single brief environmental exposure nearly 60 years in the past is still present and can be detected. Properties of potassium iodide KI: White, when stored on the light turn yellow. However, KI administration 96 h or more before 131I exposure has no significant protective effect. Lugol's iodine.

We doesn't provide iodide melting point products or service, please contact them directly and verify their companies info carefully. However, in the event of a radioiodine release too massive and widespread to be controlled by the limited stock of iodide and iodate prophylaxis drugs, then the addition of perchlorate ions to the water supply, or distribution of perchlorate tablets would serve as a cheap, efficacious, second line of defense against carcinogenic radioiodine bioaccumulation. air monitoring (4) ... Potassium Iodide Starch Paper. The recommended standard (daily) dose of KI for all school-age children is the same (65 mg). Like other iodide salts, KI forms I3− when combined with elemental iodine. [26], There have been some reports of potassium iodide treatment causing swelling of the parotid gland (one of the three glands that secrete saliva), due to its stimulatory effects on saliva production.[27]. Write review. This is not the same as blocking the thyroid's release of thyroid hormone, for which the adult dose is different (and is actually higher by a factor of 7 or 8[citation needed]), and for which KI anti-radiation pills (not a common medical treatment form of KI) are not usually available in pharmacies, or normally used in hospitals, or by physicians.

In contrast, KI administration after exposure to radioiodine induces a smaller and rapidly decreasing blockade effect. POTASSIUM IODIDE KI. in rats: 285 mg/kg (Hildebrandt), Potassium iodide [19], In 1982, the U.S. Food and Drug Administration approved potassium iodide to protect thyroid glands from radioactive iodine involving accidents or fission emergencies. Beoordeling schrijven. An aqueous solution of KI chemically dissolves potassium iodide by complexation. For protection of the thyroid against radioiodine (iodine-131) contamination, the convenient standard 130 mg KI pill is used, if available. Princess. Until drinking, the solution is normally applied to the tea, fruit juice or milk. EINECS 235-567-5. Of these products, 131I (Iodine-131) is one of the most common and is particularly dangerous to the thyroid gland because it may lead to thyroid cancer. "[40], Chernobyl also demonstrated that the need to protect the thyroid from radiation was greater than expected.
