Adsorption is the adhesion[1] of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface.[2] This process creates a film of the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent).[3] While adsorption does often precede absorption, which involves the transfer of the absorbate into the volume of the absorbent material, alternatively, adsorption is distinctly a surface phenomenon, wherein the adsorbate does not penetrate through the material surface and into the bulk of the adsorbent.[4] The term sorption encompasses both adsorption and absorption, and desorption is the reverse of sorption.

Solution

Claro, aquí tienes la respuesta paso a paso:

  1. Definición de Adsorción: La adsorción es la adhesión de átomos, iones o moléculas de un gas, líquido o sólido disuelto a una superficie. Este proceso crea una película del adsorbato en la superficie del adsorbente.

  2. Diferencia con Absorción: La adsorción se diferencia de la absorción, en la cual un fluido (el absorbato) es disuelto por o permea un líquido o sólido (el absorbente).

  3. Relación entre Adsorción y Absorción: Aunque la adsorción a menudo precede a la absorción, que implica la transferencia del absorbato al volumen del material absorbente, la adsorción es un fenómeno exclusivamente superficial, donde el adsorbato no penetra a través de la superficie del material y dentro del volumen del adsorbente.

  4. Términos Relacionados: El término sorción abarca tanto la adsorción como la absorción, y la desorción es el proceso inverso a la sorción.
