Description
Sodium Thiosulfate (Hypo) Crystals - Photographic Fixer, Water Dechlorinator & Cyanide Antidote
Sodium thiosulfate, commonly known as "Hypo," is a versatile and important inorganic chemical product, typically found as colorless, transparent pentahydrate crystals. Our product offers high-quality industrial-grade crystals whose unique chemical properties make them indispensable in several professional fields, including photography, water treatment, medical emergency, and mining.
Core Applications
Photographic Fixer
This is the most classic application of sodium thiosulfate. In the processing of traditional film and photographic paper, the unexposed silver halide remaining after development remains light-sensitive and would darken the image. Sodium thiosulfate reacts with these silver halides to form stable, water-soluble complexes, completely dissolving and washing them away from the photographic material. This permanently fixes the image, making it an essential chemical in darkroom processes.
Efficient Water Dechlorinator
In aquaculture, potable water treatment, and swimming pool maintenance, sodium thiosulfate is a safe and highly effective neutralizer for residual chlorine. It rapidly undergoes a redox reaction with leftover chlorine or hypochlorite in water, producing harmless products like sodium chloride, thereby instantly eliminating chlorine's toxicity. This protects chlorine-sensitive fish, microorganisms, and downstream water treatment equipment.
Medical Antidote
In clinical settings, sodium thiosulfate is one of the specific antidotes for cyanide poisoning. Its mechanism of action involves serving as a sulfur donor. Catalyzed by enzymes in the body, it converts the highly toxic cyanide ions into thiocyanate, which is less toxic and readily excreted in urine. It is often used in conjunction with drugs like sodium nitrite and is a critical standby medication in emergency kits and specific industrial environments.
Environmentally Friendly Reagent for Gold Leaching
In gold extraction, sodium thiosulfate is gaining increasing attention as a non-cyanide lixiviant. Catalyzed by ammonia and copper ions, it can form stable complexes with gold, dissolving it. This method offers advantages of lower toxicity and relative environmental friendliness, making it suitable for ores incompatible with cyanidation or for use in regions with stringent environmental regulations.
