Trithiocyanuric Acid Trisodium Salt (TMT) CAS 17766-26-6
Product name: Trithiocyanuric Acid Trisodium Salt (TMT)
CAS No.: 17766-26-6
EINECS No.: 241-749-5
Molecular Formula: C3N3Na3S3
Molecular Weight: 243.22
General:
Trithiocyanuric Acid Trisodium Salt (TMT) is a highly efficient, water-soluble chelating agent primarily used for the precipitation of heavy metals from industrial wastewater. Our facility principally manufactures two specifications: TMT-15 (liquid) and TMT-55 (powder). Solubility: Easily soluble in water. Stability: Should be stored in a sealed container in a cool, dry, and well-ventilated area to prevent thermal decomposition or deterioration. This product forms insoluble and stable complexes with both monovalent and divalent metal ions; compared to traditional sulfur-based treatment agents, it offers safer handling and significantly more effective results.
Specification:
Item | Standard | |
Active Assay % | 15% | 55% |
Appearance | Colorless to yellowish-red liquid | White or pale yellow crystals |
pH value | 10-12 | ≥12 |
Advantages:
High Efficiency: Exhibits exceptional chelating capabilities toward a wide range of heavy metals, including mercury, copper, cadmium, silver, lead, nickel, and tin.
Safety: Compared to traditional heavy metal precipitants—such as Sodium Dimethyldithiocarbamate (SDTC) or Sodium Sulfide—TMT demonstrates lower toxicity and offers safer handling.
Storage and Handling: TMT-55 is a white solid, while TMT-15 is a pale yellow liquid. During storage, the product must be kept away from oxidizing agents and acidic substances to prevent decomposition and degradation.
Applications:
Trisodium Trithiocyanurate is particularly well-suited for the treatment of heavy metal-containing wastewater generated by electroplating plants, battery manufacturing facilities, photographic laboratories, as well as other chemical, electronics, and metallurgical industries. It demonstrates excellent removal efficacy against most monovalent and divalent heavy metal ions. Furthermore, it is widely utilized for the solidification/stabilization of heavy metal ions found in fly ash, as well as for the remediation of heavy metal-contaminated soils.
