Studies of chronically exposed workers though have thus far failed to detect any abnormalities of thyroid function, including the uptake of iodine.To completely block the uptake of Iodine-131 by the purposeful addition of perchlorate ions to a populace's water supply, aiming at dosages of 0.5 mg/(kg d), or a water concentration of 17 ppm, would therefore be grossly inadequate at truly reducing radioiodine uptake. Potassium perchlorate is a competitive inhibitor of iodine uptake through inhibiting the sodium-iodide symporter on the thyroid follicular cell membrane. Get it as soon as Fri, Aug 21. Potassium perchlorate is prepared industrially by treating an aqueous solution of It can also be produced by bubbling chlorine gas through a solution of potassium chlorate and potassium hydroxide,Another preparation involves the electrolysis of a potassium chlorate solution, causing KClOThe conversion of solid glucose into hot gaseous COAs an oxidizer, potassium perchlorate can be used safely in the presence of In commercial use it is mixed 50/50 with potassium nitrate to create Pyrodex Treatment of thyrotoxicosis (including Graves' disease) with 600-2,000 mg potassium perchlorate (430-1,400 mg perchlorate) daily for periods of several months or longer was once common practice, particularly in Europe,Prophylaxis with perchlorate containing water at concentrations of 17 However, when the average perchlorate absorption in perchlorate plant workers subjected to the highest exposure has been estimated as approximately 0.5 mg/(kg d), as in the above paragraph, a 67% reduction of iodine uptake would be expected.
Potassium Perchlorate 325 Mesh 10 LBS. This potassium perchlorate's particle size averages -100 mesh (99%). This single precipitation reaction exploits the low solubility of KClO4, which is about 1/100 as much as the solubility of NaClO4 (209.6 g/100 mL at 25 °C).

C’est un sel inorganique toxique (puissant perturbateur endocrinien du système thyroïdien), associant du chlore et 4 atomes d’oxygène à un atome métallique (potassium) ; Comme d'autres perchlorates, ce sel est un puissant oxydant qui peut réagir avec de nombreuses substances organiques, éventuellement de manière explosive, d'où son utilisation par l'industrie de l'armement comme explosif (détonant) ou agent propulsif. 1 ml de solution = 15 gouttes = 300 mg de perchlorate de sodium. Du perchlorate de potassium administré à 1 % dans de l'eau potable à des rats Wistar femelles durant 1 à 12 mois produit à partir du 6 e mois de multiples nodules des cellules folliculaires (souvent bilatéraux, diffus et de morphologie complexe) dans la glande thyroïde [116] Perchlorate ion concentrations in a regions water supply, would need to be much higher, at least 7.15 mg/kg of body weight per day or a water concentration of 250 The continual distribution of perchlorate tablets or the addition of perchlorate to the water supply would need to continue for no less than 80–90 days, beginning immediately after the initial release of radioiodine was detected, after 80–90 days had passed released radioactive iodine-131 would have decayed to less than 0.1% of its initial quantity at which time the danger from biouptake of iodine-131 is essentially over.Potassium chlorate(VII); Perchloric acid, potassium salt; peroidinInChI=1S/ClHO4.K/c2-1(3,4)5;/h(H,2,3,4,5);/q;+1/p-1Except where otherwise noted, data are given for materials in their Helmut Vogt, Jan Balej, John E.
