Definition - What does Adsorbent mean?
An adsorbent is an insoluble material coated by liquid on the surface, including capillaries and pores. A material is said to be adsorbent when it has the capacity to contain a definite amount of liquid in small chambers similar to a sponge.
Adsorbents play a vital role in chemical absorption, which takes place when a certain substance is trapped on a material's surface.
Corrosionpedia explains Adsorbent
Adsorption is the process of a liquid or gas accumulating on a liquid or solid surface, building an atomic or molecular film. It is substantially different from the process of absorption, where a substance goes through diffusion into a solid or liquid to produce a solution.
Adsorbents, through the process of adsorption, are operative in almost all systems such as chemical, biological and physical. They also play a major role in industry, with many applications such as in water purification, activated charcoal and synthetic resins.
Adsorbents are also useful in causing waste heat to produce cold water intended for air conditioning as well as other processes.
In industry, adsorbent composition is very beneficial in slowing corrosion in various equipment and machinery, such as in mufflers. For instance, internal corrosion of mufflers made of metal along with combustion engines is prevented by sustaining the external void area of adsorbent mass combined with crystalline zeolites and other crystal structures that have a synergistic effect in retarding corrosion.
