APPLICATION
APPLICATION AREA
The following is an introduction to the application areas of the product
Industrial treatment
Metal extraction
Environmentally friendly leaching agent, instead of cyanide, forms a stable complex ([Au(S₂O₃)₂]³⁻) with gold ions in gold deposits, suitable for the treatment of carbon-containing or complex ores.
Water treatment
Residual chlorine neutralization
For swimming pools, drinking water and wastewater treatment, rapid reduction of hypochlorous acid (HClO) and chloramines, to prevent corrosion of pipes or irritation of the human body. Reaction formula:
Na2S2O3+4Cl2+5H2O→2NaHSO4+8HCl
Medical field
Antidote for cyanide poisoning
As a highly effective antidote to cyanide poisoning, sodium thiosulfate combines with cyanide to form low-toxicity thiocyanate (SCN⁻) by providing a source of sulfur, which is excreted through the kidneys. It is usually used in combination with sodium nitrite to enhance the efficacy.
Photographic industry
Core component of fixer
In traditional film development, sodium thiosulfate dissolves the unexposed silver halide (AgBr/AgI) to form a soluble complex (such as Na₃[Ag(S₂O₃)₂]), which fixes the image and prevents further exposure. The digital age is still used for art photography and film development.
