Product Application

Photography & Film Industry :

Essential Fixing Agent : Dissolves unexposed silver halides. An indispensable chemical in film and paper processing, requiring high-purity photographic grade .

Water Treatment & Environmental Protection :

Dechlorination Agent : Widely used to remove residual chlorine ​ from tap water, cooling water, and treated wastewater to protect downstream biological systems and sensitive equipment.

Cyanide Waste Treatment : Treats cyanide-bearing wastewater from electroplating and mining, converting it to less toxic thiocyanates.

Textile & Paper Industries :

Anti-chlor / Bleach Neutralizer : Used after bleaching of textiles and pulp to neutralize and remove residual chlorine or peroxide , preventing fiber degradation and yellowing.

Gold Mining & Extraction :

Eco-Friendly Gold Lixiviant : Serves as a cyanide-free alternative ​ for gold extraction from ores, particularly effective for carbonaceous and arsenic-bearing refractory ores. A key technology for "greener" mining.

Pharmaceuticals & Chemical Manufacturing :

Antidote : Used in clinical emergency treatment (cyanide poisoning).

Chemical Reagent & Raw Material : Used in the production of other sulfur compounds and as a standard reducing agent in iodometric titrations ​ (analytical chemistry).

Other Applications :

Leather tanning, electroplating bath additive, water purifier, and auxiliary in flue gas desulfurization.
