Adsorbent materials facilitate conversion of a liquid to a semisolid phase and are used after the skimming operation to clean the remaining oil. These adsorbents can be natural organic, natural inorganic, or synthetic materials.

Where is adsorbent used?

Adsorbents are used in medicine mainly for the treatment of acute poisoning, whereas other extracorporeal techniques based on physico-chemical principles, such as dialysis and ultrafiltration, currently have much wider clinical applications [1].

What is the reason for adsorption?

Adsorption is caused by London Dispersion Forces, a type of Van der Waals Force which exists between molecules. The force acts in a similar way to gravitational forces between planets.
