Application

In the realm of photography, sodium thiosulfate acts as a fixing agent, playing a crucial role in the development process. During tanning, it takes on the functions of a reducing agent and mordant for dichromate, facilitating the chemical reactions involved in leather processing.

 

Industrial wastewater often contains various heavy metal ions such as lead, etc. These heavy metal ions pose great harm to the environment and organisms. Sodium thiosulfate can form insoluble sulfide precipitates with certain heavy metal ions, thereby removing heavy metal ions from wastewater to achieve the purpose of purifying wastewater and reducing the pollution of wastewater to the environment.
