What is Carbon?
Carbon (CAS 7440-44-0) is a foundational industrial element supplied primarily as activated carbon, a processed form engineered for high surface area adsorption.
Where is Carbon used?
- Water treatment: removes chlorine, organic contaminants, and taste-and-odor compounds from municipal supplies
- Pharmaceutical manufacturing: decolorizes and purifies active ingredient streams
- Food and beverage production: clarifies edible oils, sugars, and alcohols by adsorbing color bodies and impurities
- Mining: captures dissolved gold from cyanide leach solutions in carbon-in-pulp and carbon-in-leach circuits
- It functions as a purification agent.
Commercial specifications
- Bulk supply standard; smaller packaging for laboratory procurement
