Physicochemical Properties

(Typical values; can be adjusted according to your required specification.)

Applications

1. Water Treatment & Dechlorination
   • Neutralizes residual chlorine in municipal and industrial water.
   • Used in boiler water, cooling water and wastewater treatment systems to protect downstream equipment and processes.
2. Photographic Industry
   • Acts as a classic fixer for photographic films and papers, dissolving unexposed silver halides.
   • Used in traditional darkroom processes and some specialized imaging applications.
3. Mining & Metallurgy
   • Participates in cyanide-related processes and detoxification in precious metal extraction.
   • Helps reduce toxicity in cyanide-bearing effluents when properly used in engineered systems.
4. Chemical & Pharmaceutical Processes
   • Functions as a reducing agent and analytical reagent in laboratories and process lines.
   • Used as an auxiliary chemical in some pharmaceutical and diagnostic applications (according to local regulations).
5. Textile & Pulp Industries
   • Applied as a reducing and dechlorinating agent after bleaching steps.
   • Helps protect fibers and improve final product quality by removing residual oxidants.

Storage Conditions

• Store in a cool, dry, well-ventilated warehouse.
• Keep containers tightly closed to prevent moisture uptake and caking.
• Protect from direct sunlight, rain and high temperature.
• Keep away from strong acids and strong oxidizing agents.
• Recommended storage temperature: ambient, avoiding extremes.
• Under proper storage, typical shelf life is 24 months from production date.

Safety Precautions

• Sodium Thiosulfate is generally considered to have low acute toxicity, but good industrial hygiene practices must always be followed.
• Avoid creating or inhaling dust; use local exhaust ventilation where dust may be generated.
• Wear appropriate personal protective equipment (PPE): safety glasses or goggles, dust mask/respirator, gloves and protective work clothing.
• Avoid contact with eyes and prolonged skin contact. In case of contact, rinse with plenty of water.
• Do not eat, drink or smoke in the working area; wash hands thoroughly after handling.
• In case of large spills, collect the material mechanically and avoid discharge into natural water bodies.
• Dispose of material and packaging in accordance with local regulations.
