Key Features & Characteristics:

1. High Chelating Efficiency: Potassium Dimethyl Dithiocarbamate (KDD) is a powerful chelator for heavy metals, effectively binding with metal ions to prevent them from causing contamination or toxic effects.

2. Appearance & Odor: The product is a clear green liquid, often characterized by its distinct ammonia odor, which is typical for dithiocarbamate compounds.

3. High Alkalinity: The product has a high pH range (11.5 - 14), indicating its strong alkaline nature, which can be important in various chemical processes and treatment applications.

4. Versatile Applications: KDD is widely used in heavy metal removal, especially in water treatment, mining, and industrial processes, where it can act as an effective agent for metal ion sequestration.

5. Specific Gravity: The density of 1.2 means that it is relatively dense compared to water, a characteristic that may influence its handling and mixing in aqueous solutions.

Applications:

• Heavy Metal Chelation: KDD is primarily used to capture and sequester heavy metals such as copper, lead, mercury, and cadmium, preventing environmental pollution.
• Water Treatment: It's often employed in water treatment plants to remove toxic metal ions from wastewater before discharge.
• Agriculture & Soil Remediation: KDD can be used to detoxify soils contaminated with heavy metals and improve agricultural practices.
• Mining and Metal Processing: Used in the mining industry for the selective extraction of metals and reducing the impact of mining waste.

Handling and Safety:

• Protective Measures: Due to its high pH and ammonia odor, proper personal protective equipment (PPE) should be used when handling KDD, including gloves and eye protection.
• Storage: Store in a cool, dry place away from direct sunlight and incompatible materials to ensure stability and safety.
