Adsorption technology is a process where molecules from a gas or liquid adhere to the surface of a solid material, known as an adsorbent. This technique is widely used for purifying air and water, capturing pollutants, and separating chemical compounds. Common adsorbents include activated carbon and silica gel, which have large surface areas that enhance their ability to attract and hold particles. The effectiveness of adsorption depends on various factors, including temperature, pressure, and the nature of the adsorbent. Applications of adsorption technology can be found in industries such as environmental engineering, chemical processing, and pharmaceuticals, making it a vital tool for improving product quality and safety.
