Specification:

Application:
-Photographic Processing:
 Sodium thiosulfate is also used as a fixer in photography. The negative plate or film obtained at the end of photographic development with a reducing agent (i.e., potassium ferrous oxalate, pyrogallol) contains Ag, Br which has not been light-activated and reduced to Ag metal. This is treated with sodium thiosulfate solution so that Ag, Br is removed as a soluble complex compound. This process is known as "fixing" of the negative plate or film.
-Water treatment industry :   as water purifying agent
-Paper industry                    :    as dechlorination agent  
-Healthcare:
Sodium thiosulfate is used to treat arsenic poisoning, primarily because it is relatively inexpensive and non-toxic. Sodium thiosulfate is proven to be effective in the treatment of copper poisoning when it is applied together with sodium molybdate. It has been also recommended in the treatment of cyanide poisoning.
-Gold Extraction:
Sodium thiosulfate is employed in the extraction of gold and silver. Sodium thiosulfate forms a strong complex compound during reactions with gold and silver. The newly formed substances are highly soluble in water, so the target metals (gold and silver) can be leached by thiosulfate.
-Aquaculture:
Sodium thiosulfate is used as a dechlorination agent in neutralizing chlorine and iodine solutions at aquaculture or hatchery facilities. Chlorine is a toxic element, and excess chlorine could be harmful to fish and crustaceans, so it is important to remove chlorine by disinfecting tanks and equipment using sodium thiosulfate before introducing the stock
-Textile industry:
 Sodium thiosulfate is applied as an antichlor to remove excess chlorine from bleached articles in the textile industry.
