Product Description: Sodium Dimethyl Dithiocarbamate is a highly versatile organic sulfur compound with wide-ranging applications. It serves as a fungicide, pesticide, and is integral in the pharmaceutical industry for synthesizing various drugs. Additionally, SDMDTC is an essential intermediate in the production of other dithiocarbamates and rubber chemicals.

Key Features:

• Versatility: Widely utilized in agriculture, pharmaceuticals, and chemical synthesis.
• Efficiency: Highly effective as a biocide for controlling fungal growth and as a potent pesticide.
• Safety: Must be handled with care due to its potential toxicity.

Applications:

• Mining Flotation:

  • SDMDTC acts as a collector in froth flotation, enhancing the separation of valuable minerals from waste rock (gangue). Its ability to form metal ion complexes aids in the selective flotation of specific ores.

• Fly Ash Treatment:

  • Used for immobilizing heavy metals in fly ash from coal combustion, SDMDTC reduces their mobility and environmental impact. This is particularly crucial when fly ash is repurposed in cement production or as a soil amendment.

• Heavy Metal Treatment:

  • Due to its exceptional chelating properties, SDMDTC forms stable complexes with heavy metal ions. This makes it ideal for removing heavy metals from industrial wastewater and contaminated soils in environmental remediation.
  • Cobalt Removal in Zinc Smelting (Hydrometallurgy):
    • In zinc hydrometallurgical purification, SDMDTC serves as a selective extractant for cobalt, especially in zinc sulfate solutions. This process ensures the removal of cobalt impurities, meeting the purity standards for zinc products.
    • The selective complexation of cobalt by SDMDTC not only facilitates the purification process but also enables the recovery of cobalt as a valuable byproduct.

• Agricultural Soil Treatment:

  • SDMDTC is used in remediating soils contaminated with heavy metals, forming complexes that reduce metal bioavailability and mobility.

• Industrial Wastewater Treatment:

  • Applied in industrial settings, SDMDTC treats wastewater containing heavy metals, ensuring compliance with regulatory discharge standards.

Safety Information:

• Always wear appropriate personal protective equipment (PPE) when handling SDMDTC.
• Avoid inhalation, ingestion, and skin contact. Ensure use in a well-ventilated area.

Storage Conditions:

• Store in a cool, dry place, ensuring the temperature remains consistent and avoiding proximity to heat sources and direct sunlight.
• Keep the container tightly sealed at all times to preserve the product's integrity and prevent contamination or degradation.
