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] .

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

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.

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.

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]

2025年1月28日 · It also neglects the lateral interaction between the adsorbed molecule and the limited applicability in low adsorbate concentrating pressure [22, 23]. 2.2.2 Freundlich isotherm. Unlike Langmuir, this empirical model is perfectly capable of being used in multilayer adsorption within heterogeneous sites . The assumption is that the adsorption ...

ADSORB definition: 1. to cause a substance, usually a gas, to form a very thin layer on the surface of another…. Learn more.

The meaning of ADSORPTION is the adhesion in an extremely thin layer of molecules (as of gases, solutes, or liquids) to the surfaces of solid bodies or liquids with which they are in contact.

Adsorption is often described as a surface phenomenon where particles are attached to the top layer of material. It normally involves the molecules, atoms or even ions of a gas, liquid or solid in a dissolved state that is attached to the surface. Adsorption is mainly a …

2007年8月7日 · Adsorption is a different process from absorption, in which a substance diffuses into a liquid or solid to form a solution. In adsorption, the gas or liquid particles bind to the solid or liquid surface that is termed the adsorbent. The particles …
