Description
Occurs when one substance adheres to the surface of another, called the adsorbent. The adsorption bonding forces are weak van der Waals bonds and can usually be reversed to regenerate the absorbent's capacity. Adsorbents are used to remove pollutants, odors, tastes, colors and moisture from gases and liquids. Common adsorbents are Activated carbon, Activated alumina, clays, zeolites, and Silica gel. The adsorption process is used to produce lake pigments by precipitating dyes on a substrate, such as aluminum hydroxide. An often confused term, Absorption, refers to the penetration of one substance into another.
