What Is Activated Carbon?

Activated carbon, also known as activated charcoal, is a highly porous substance that has been treated with oxygen to open up millions of tiny pores between carbon atoms. These pores help to increase the surface area of the carbon, making it highly effective in adsorbing (not absorbing) pollutants, chemicals, and toxins from air and water.

Activated carbon is commonly used in a range of industries, including water treatment, air purification, food and beverage processing, pharmaceuticals, and gold extraction, to name just a few.

In water treatment, activated carbon filters are used to remove impurities like chlorine, pesticides, and other chemicals. By adsorbing the impurities, activated carbon can improve the taste, odor, and color of drinking water, making it safer and more pleasant to consume.

In air purification, activated carbon filters can remove harmful chemicals like volatile organic compounds (VOCs) and household odors. These filters are commonly used in air purifiers, respirators, and gas masks.

The food industry also uses activated carbon in the processing of foods and beverages. Activated carbon can remove impurities like pigments, odors, and flavors, improving the quality of the final product.

Pharmaceutical companies use activated carbon in the production of drugs to remove impurities and contaminants. This helps to ensure the purity and effectiveness of the final product.

In gold extraction, activated carbon is used to adsorb the gold from cyanide solutions, effectively extracting the gold from the solution.

Overall, activated carbon is a versatile and effective substance that plays an important role in a range of industries. Its ability to adsorb pollutants, chemicals, and toxins makes it an important tool in the quest for cleaner air and water, and safer, higher-quality products.
