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] .

2021年7月15日 · Adsorption occurs when ions, atoms, or molecules adhere to a surface. The substance adsorbed onto the surface is called the adsorbate. The substance with the surface is called the adsorbent. Adsorption is an exothermic process because energy is released when the adsorbate sticks to the adsorbent.

2025年1月24日 · adsorption, capability of all solid substances to attract to their surfaces molecules of gases or solutions with which they are in contact. Solids that are used to adsorb gases or dissolved substances are called adsorbents; the adsorbed molecules are usually referred to collectively as the adsorbate.

The meaning of ADSORB is to take up and hold by adsorption.

Adsorption refers to the process of adhesion of molecules or ions to a solid surface. It is the phenomenon where substances from a fluid phase, such as gases or liquids, accumulate on the surface of a solid material. [1-4]

Absorption is the process in which a fluid is dissolved by a liquid or a solid (absorbent). Adsorption is the process in which atoms, ions or molecules from a substance (it could be gas, liquid or dissolved solid) adhere to a surface of the adsorbent.

The deposition of molecular species onto a surface is known as adsorption. Adsorbate refers to the molecular species that gets adsorbed on the surface, whereas adsorbent refers to the surface on which adsorption happens. Clay, silica gel, colloids, …
