Sodium trithiocyanurate

Sodium trithiocyanurate (CAS 17766-26-6), commercially known as TMT, is the trisodium salt of trithiocyanuric acid used to precipitate and immobilize heavy metal ions in industrial processes.

Where is Sodium trithiocyanurate used?

• Industrial wastewater treatment: precipitates heavy metals such as mercury and lead
• Effluent streams: targets cadmium and copper, enabling compliance with discharge limits
• Mining and mineral processing: removes residual metal contaminants from process water
• Tailings pond runoff and electroplating wastewater: applied where hydroxide precipitation alone fails to meet regulatory thresholds
• Metal smelting and refining: polishing agent in final effluent treatment
• It reacts selectively with dissolved metals to form stable, insoluble complexes that can be separated from liquid streams.

Commercial specifications

• Aqueous solution, most commonly at 15% concentration
• Quality characterized by active content and heavy metal precipitation efficacy
