Adsorbents

Adsorbents are materials used to capture or remove substances from liquids or gases by attracting and holding them on their surface. Unlike absorption, where a substance is absorbed throughout, adsorption involves particles sticking to the surface of the adsorbent. Common examples include activated carbon, which is used in water purification and air filters, and silica gel in packaging to control moisture. Their effectiveness depends on surface area, pore size, and chemical properties, making them vital in environmental cleanup, air and water treatment, and chemical processing.
