ADSORBENT OVERVIEW

Adsorption refers to the concentration of a fluid component (gas or liquid phase) onto the surfaces of a solid. This can be a purely physical interaction between the adsorbent and adsorbate species (physical adsorption or physisorption), or can involve a chemical reaction (chemical adsorption or chemisorption). Adsorbents whose reactivity is based on physisorption can be divided into two basic categories. The first are oxygen-containing compounds such as silica gel, activated alumina, and zeolitic molecular sieves. These agents are hydrophilic in nature and will show a preference towards the adsorption of polar compounds. The second group contains carbon as the major component. This includes activated carbon, activated coke, and carbon molecular sieves. These adsorbents are hydrophobic in nature and are therefore primarily used to remove organics from gases and aqueous streams.
