Absorption is a condition in which something takes in another substance. It is a physical or chemical phenomenon or process, in which atoms, molecules, or ions enter in the inner part (called "bulk") of a gas, liquid, or solid material.. This is a different process from adsorption.Molecules undergoing absorption are going deep into the volume of the material, …

In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. This is a different process from adsorption, since molecules undergoing absorption are taken up by the volume, not by the surface (as in the case for adsorption).A more general term is sorption, which covers …

04/12/2010 · In chemistry, absorption is a process by which a substance incorporated in one state is transferred into another substance of a different state (e.g., gases being absorbed by a liquid or liquids being absorbed by a solid).As an industrial process, the most commonly encountered use of absorption is for the separation and/or purification of a gas mixture by the …

Absorption : Processus selon lequel un matériau (absorbat) est retenu par un autre (absorbant) ; il peut s'agir de la solution physique d'un gaz, d'un liquide ou d'un solide dans un liquide, de la fixation de molécules d'un gaz, d'une vapeur, d'un liquide ou d'une substance dissoute à une surface solide par des forces physiques, etc. En spectrophotométrie, l'absorption de la lumière …
