The Science Behind Activated Carbon
Activated carbon is a highly effective material for removing impurities from water. It is made from organic materials such as coconut shells or coal, which are heated to high temperatures to create a highly porous structure. This structure allows the activated carbon to attract and trap impurities in the water, including chlorine, lead, and other organic compounds.
The effectiveness of activated carbon in removing impurities from water is due to its high surface area and chemical reactivity. The surface area of activated carbon is incredibly high, with some materials having a surface area of up to 1,000 square meters per gram. This allows the activated carbon to come into contact with a large amount of water, increasing its effectiveness in removing impurities.
How Activated Carbon Removes Impurities
Activated carbon removes impurities from water through a process called adsorption. Adsorption is a chemical reaction that occurs when a substance attracts and holds onto another substance. In the case of activated carbon, it attracts and holds onto impurities in the water, such as chlorine and lead.
The adsorption process occurs through a combination of physical and chemical forces. The physical forces include van der Waals forces, which are weak intermolecular forces that occur between molecules. The chemical forces include electrostatic forces, which occur between charged particles.
