sodium cyanide systemic agent niosh cdcnext, administer 0.75 ml per pound body weight of 25% sodium thiosulfate (1.65 ml per kilogram body weight of 25% sodium thiosulfate) intravenously over a period of 10 minutes. if physical findings persist for 30 minutes after antidote administration, sodium nitrite and sodium thiosulfate may be readministered at half their original respectivesodium thiosulfate sodium thiosulfate and ammonium thiosulfate are a component of an alternative lixiviants to cyanide for extraction of g. thiosulfate forms strong soluble complexes with g(i) ions, [au(s 2 o 3) 2] 3. the advantages of this approach are that (i) thiosulfate is essentially nontoxic and (ii) that ore types that are refractory to gsodium sulfide hna2s+ pubchemheparinized rat blood containing sodium (35)ssulfide was perfused through isolated rat lungs, kidney or liver. the rate and extent of sulfide oxidation varied from one organ to another. in the isolated perfused lung system, (35)ssulfide was oxidized slowly to (35)sthiosulfate; only small amounts of (35)ssulfate were detectable, possibly due to the absence of sulfide oxidase.

home page urologythe society of genitourinary reconstructive surgeons (gurs) and urology are excited to announce that the g journal has become the official journal of gurs. more. in the authors words interview with thomas stout, author of g journal publication "a visual scale for improving communication when describing gross hematuria"sodium thiosulfate (na2s2o3) properties, formulasodium thiosulfate salts are used as photographic fixers due to the ability of the thiosulfate ions to react with silver halides, which make up photographic emulsions. ammonium thiosulfate and sodium thiosulfate make up lixiviants (liquid mediums used in hydrometallurgy) which are used in the extraction of g from its ores.g cyanidation g cyanidation (also known as the cyanide process or the macarthurforrest process) is a hydrometallurgical technique for extracting g from lowgrade ore by converting the g to a watersoluble coordination complex.it is the most commonly used leaching process for g extraction.. production of reagents for mineral processing to recover g, copper, zinc and silver representshome page [.labchem ]our product line consists of chemical solutions prepared to exact quality standards and certified for use in laboratories and production processes. we regularly produce chemical solutions to specifications designed by government and regulatory bodies, commercial and trade associations, and the specific needs of individual users and businesses.
