Sorbent
A sorbent is a material used to absorb or adsorb liquids or gases. Examples include: How do sorbents work? A Chemical spill absorbing mat pads to act as a sorbent must attract oil preferentially to water i.e. – it should be oleophilic and hydrophobic. Sorbent materials must act by adsorption or less commonly by absorption. Both adsorb material, as well as absorbents, incorporate the oil or other liquid to be recovered into the body of the material.
