Activated Carbon
Activated carbon, also known as activated charcoal, is a highly porous material with a vast surface area, making it highly effective at adsorbing impurities and contaminants. It is commonly derived from carbon-rich materials like wood, coal, or coconut shells. The activation process involves heating the carbon in the presence of gases to create tiny pores, which increase its surface area and adsorption capacity. Activated carbon is widely used in water purification, air filtration, and even medical treatments, such as poisoning antidotes.
