1,3,5-Triazine-2,4,6-trithiol trisodium salt is a specialty chelating agent primarily used in water and wastewater treatment to bind and precipitate heavy metals such as lead, cadmium, mercury, copper, and others. It forms stable, insoluble complexes that facilitate the removal of these contaminants, helping to meet environmental regulations and protect water sources. This compound is also applied in the paper and pulp industry to sequester metal ions, improving production processes and enhancing bleaching efficiency by preventing metal-catalyzed degradation. In the textile industry, it aids in dyeing processes by controlling metal impurities and improving fiber properties.
