The US Food and Drug Administration approved a selenium supplement to animal diets; the most common form is sodium selenite for pet foods. According to one article, "not much was known about which selenium compounds to approve for use in animal feeds when the decisions were made back in the 1970s ..
ATC code A12 Mineral supplements is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
Selenium yeast is a feed additive for livestock, used to increase the selenium content in their fodder. It is a form of selenium currently approved for human consumption in the EU and Britain. [1] Inorganic forms of selenium are used in feeds (namely sodium selenate and sodium selenite, which appear to work
Sodium selenate is produced by oxidation of selenium, first with nitric acid, producing selenous acid. The selenous acid is neutralized to form sodium selenite. The sodium selenite is oxidized in a basic medium hydrogen peroxide to form a selenate, which is then spray-dried. [3] Se + 2HNO 3 → H 2 SeO 3 + NO + NO 2 H 2 SeO 3 + Na 2 CO 3 → Na ...
Selenium disulfide has been used in shampoo as an antidandruff agent, an inhibitor in polymer chemistry, a glass dye, and a reducing agent in fireworks. [ 6 ] Selenium trioxide may be synthesized by dehydrating selenic acid , H 2 SeO 4 , which is itself produced by the oxidation of selenium dioxide with hydrogen peroxide : [ 8 ]
Opting for low-sodium foods, defined as 140 mg of sodium or less per serving, can help keep your salt intake at bay. Even choosing items labeled "reduced sodium" or "no salt added" can make a ...
Selenite broth was originated by Leifson, [2] while observing good recovery of Salmonella spp. and reduced growth of fecal coliforms. Selenite broth is used as a selective enrichment for the cultivation of Salmonella spp. that may be present in small numbers and competing with intestinal flora. This medium must not be autoclaved. Once prepared ...
Unlike sulfate, selenate is a somewhat good oxidizer; it can be reduced to selenite or selenium. [3] In strongly acidic conditions, the hydrogen selenate ion, HSeO − 4, is formed. [4] It corresponds to the selenic acid, H 2 SeO 4, which is a strong acid and can in its concentrated form dissolve gold. [5] The element selenium exhibits several ...
