Physical and Chemical Adsorption and its Applications

WebChemical adsorption, or chemisorption, is a process resulting from a chemical bond between adsorbate molecules and specific surface locations on a material, known as active sites. This interaction is much stronger than physical adsorption, or physisorption, which takes place on all surfaces if temperature and pressure conditions are favorable. WebAdsorption can be used to treat waste streams or purify valuable components of a feed. This article describes both equilibrium and mass-transfer considerations, and reviews the …
