What is activated charcoal and how does it differ from regular charcoal?
Activated charcoal, also known as activated carbon, is a type of charcoal that has been treated to increase its surface area and adsorption capacity. This process, called activation, involves heating the charcoal to high temperatures in the absence of oxygen, which opens up the pores and creates a large internal surface area. As a result, activated charcoal is able to attract and hold onto a wide range of substances, including chemicals, heavy metals, and gases, making it a versatile and effective filter medium.
The key difference between activated charcoal and regular charcoal is the level of activation, which affects their respective adsorption capacities. Regular charcoal, such as the kind used for barbecues, has a relatively low surface area and is not suitable for filtering or purifying substances. In contrast, activated charcoal has a highly developed internal surface area, which enables it to effectively remove impurities and contaminants from liquids and gases. This makes activated charcoal a popular ingredient in water filters, air purifiers, and skincare products, among other applications.
