pH: 7-9. [9] It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. Slightly at 25°C. [28], The use of a particular 'Iodine tablet' used in portable water purification has also been determined as somewhat effective at reducing radioiodine uptake. {Merck Index - © 1952 by Merck & Co., Inc.}. Thyroid iodine uptake blockade with potassium iodide is used in nuclear medicine scintigraphy and therapy with some radioiodinated compounds that are not targeted to the thyroid, such as iobenguane (MIBG), which is used to image or treat neural tissue tumors, or iodinated fibrinogen, which is used in fibrinogen scans to investigate clotting. Comparison of Iodide-125 and Ruthenium-106 Brachytherapy in the Treatment of Choroidal Melanomas. The iodine atom has a radius of 140 pm and a Van der Waals radius of 198 pm. [citation needed], KI is used with silver nitrate to make silver iodide (AgI), an important chemical in film photography. However, for several fluorophores addition of KI in μM-mM concentrations results in increase of fluorescence intensity, and iodide acts as fluorescence enhancer.[31]. 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. Tablets of potassium iodide are supplied for emergency purposes related to blockade of radioiodine uptake, a common form of radiation poisoning due to environmental contamination by the short-lived fission product 131I. K9. water, 22 ml. In the developing world it is also used to treat skin sporotrichosis and phycomycosis. 62K1064 – you will only find the COO if Iodine forms compounds with many elements, but is less active than the other halogens. 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. Potassium iodide CAS 7681-11-0 for analysis EMSURE® ISO,Reag. alcohol, 8 ml. This method of delivering potassium iodide does not require a method to weigh out the potassium iodide so it can be used in an emergency situation. Incompat. Potassium iodide [7681-11-0]. Aged and impure samples are yellow because of the slow oxidation of the salt to potassium carbonate and elemental iodine.[32]. Effects of meso-2,3-dimercaptosuccinic acid, potassium iodide and chlorophyll on lead accumulation in male mice. Site Use Terms Potassium is the seventh most abundant element on earth. neutral or, usually, slightly alkaline. All Rights Reserved. The origin of the element's name comes from the English word 'potash,' meaning pot ashes, and the Arabic word qali, which means alkali. In a small study on human subjects, who for each of their 90-day trial, ingested four 20 milligram tetraglycine hydroperiodide (TGHP) water tablets, with each tablet releasing 8 milligrams (ppm) of free titratable iodine;[29] it was found that the biological uptake of radioactive iodine in these human subjects dropped to, and remained at, a value of less than 2% the radioiodine uptake rate of that observed in control subjects who went fully exposed to radioiodine without treatment.[30].

[citation needed] In an accidental event or attack on a nuclear power plant, or in nuclear bomb fallout, volatile fission product radionuclides may be released. Ph Eur - Find MSDS or SDS, a COA, data sheets and more information. Caution: Iodism occurs in sensitive individuals. It dissolves readily in chloroform, carbon tetrachloride, or carbon disulfide. Keep patient warm.Seek immediate medical advice.After skin contactImmediately wash with water and soap and rinse thoroughly.Seek immediate medical advice.After eye contactRinse opened eye for several minutes under running water. Copyright © 2020 Multiply Media, LLC. Potassium iodide solns. water gives 30 ml. » Potassium Iodide contains not less than 99.0 percent and not more than 101.5 percent of KI, calculated on the dried basis. Through this reaction, iodine is used in redox titrations. Potassium iodide is a possible teratogen. [3] It is given by mouth. Potassium iodide is neutral. In 2017, the Dutch government distributed pills to hundreds of thousands of residents who lived within a certain distance of nuclear power plants and met some other criteria. In contrast, KI administration after exposure to radioiodine induces a smaller and rapidly decreasing blockade effect. Aqueous KI3, "Lugol's solution", is used as a disinfectant and as an etchant for gold surfaces. glycol. Who is the longest reigning WWE Champion of all time? readily dissolve elemental iodine. 105043 Potassium iodide for analysis Cat.No. In its elemental form, iodine has a lustrous metallic gray appearance as a solid and a violet appearance as a gas or liquid solution. It is a cough suppressant with sedative, dissociative, and stimulant properties (at higher doses) and it is the active ingredient in many over-the-c...Keywords: Thin layer chromatography. boil. [4] In the developing world it is also used to treat skin sporotrichosis and phycomycosis. The ingestion of goitrogen drugs is, much like potassium iodide also not without its dangers, such as hypothyroidism. The particle size distribution (granulometry) of potassium iodide by the sieve analysis method was found to be in the range of 225 micrometer to >500 micrometer. See reverse side of invoice or packing slip for additional terms and conditions of sale.
So any solution of potassium iodide These compounds contain iodine, but not in the iodide form. Pricing & availability is not currently available. Personal precautions, protective equipment and emergency proceduresWear protective equipment. [4], Common side effects include vomiting, diarrhea, abdominal pain, rash, and swelling of the salivary glands. It crystallises in the sodium chloride structure. Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. Commercially available iobenguane is labeled with iodine-123, and product labeling recommends administration of potassium iodide 1 hour prior to administration of the radiopharmaceutical for all age groups,[16] while the European Association of Nuclear Medicine recommends (for iobenguane labeled with either isotope), that potassium iodide administration begin one day prior to radiopharmaceutical administration, and continue until the day following the injection, with the exception of new-borns, who do not require potassium iodide doses following radiopharmaceutical injection. High purity, submicron and nanopowder forms may be considered.

"[20] Consequently, far more people than anticipated were affected by the radiation, which caused the United Nations to report in 2002 that "The number of people with thyroid cancer... has exceeded expectations. It is produced industrially by treating KOH with iodine.[32]. KI crystals are simply added to water until no more KI will dissolve and instead sits at the bottom of the container.

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. © 2020 Merck KGaA, Darmstadt, Germany and/or its affiliates. What is the dispersion medium of mayonnaise? Kowalsky RJ, Falen, SW. Radiopharmaceuticals in Nuclear Pharmacy and Nuclear Medicine.
[2][3] As a medication it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used. is Neither SSKI or KI tablets are used as nutritional supplements, since the nutritional requirement for iodine is only 150 micrograms (0.15 mg) of iodide per day. Potassium iodide's (KI) value as a radiation protective (thyroid blocking) agent was demonstrated following the Chernobyl nuclear reactor disaster in April, 1986, a saturated solution of potassium iodide (SSKI) was administered to 10.5 million children and 7 million adults in Poland[25][38] as a preventative measure against accumulation of radioactive 131I in the thyroid gland.
