99. Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride. 4.2 out of 5 stars 35. It impedes the accumulation of iodide in the thyroid, which blocks thyroid hormone production. 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.
Your recently viewed items and featured recommendations It's also used in whistles, strobes, waterfalls and many other pyrotechnic devices. ), Oxford:Butterworth-Heinemann.

This Perchlorate contains a small amount of Cabosil to help minimize clumping and keep the mixture free-flowing but is … Potassium perchlorate has, in the past, been used therapeutically to treat hyperthyroidism resulting from Graves' disease. Potassium perchlorate is a competitive inhibitor of iodine uptake through inhibiting the sodium-iodide symporter on the thyroid follicular cell membrane. 1 ml de solution = 15 gouttes = 300 mg de perchlorate de sodium. Korea, Republic of The perchlorate ion is the … 99% technical grade purity. Potassium Perchlorate is the potassium salt of perchloric acid and a member of the Hofmeister ions series with thyroid blocking properties. 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). Get it as soon as Fri, Aug 21. 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.

Le perchlorate de potassium est un produit chimique, composé du potassium, de formule KClO4. 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.
