Adsorption - Wikipedia
WebAdsorption 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] .
Adsorbers – Visual Encyclopedia of Chemical Engineering Equipment
WebAdsorption Theory. This animation exemplifies the basic process of adsorption. Material from the liquid phase is concentrated on the surface of the solid. The adsorbing phase, which is a solid in the animation above, is called the adsorbent, and the material being adsorbed at the surface of that phase is the adsorbate.
Adsorbent Definition & Meaning - Merriam-Webster
WebOct 31, 2023 · The meaning of ADSORBENT is a usually solid substance that adsorbs another substance.
Adsorption | Definition, Types, & Facts | Britannica
Webadsorption, 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.
Adsorbent - an overview | ScienceDirect Topics
WebAn adsorbent is a solid substance used to remove contaminants from liquid or gas that can harm the environment. At present, researchers are looking for low-cost adsorbents as they require less processing and are abundant in nature compared to commercial adsorbents.
Adsorbent - an overview | ScienceDirect Topics
WebProperties of a suitable adsorbent are high selectivity, high absorption capacity, long life, and low cost. Different adsorbent possesses various properties divers as its active surface, pore diameter, quality of pore distribution, and surface functional group.
Adsorption: Definition, Types, Examples, and Applications
WebIt is the phenomenon where substances from a fluid phase, such as gases or liquids, accumulate on the surface of a solid material. [1-4] Adsorption is driven by attractive forces between the adsorbate (the substance being adsorbed) …

What is Adsorption? - The International Adsorption Society
WebThe adsorbent is the separating agent used to express the difference between molecules in a mixture: adsorption equilibrium or kinetics. Adsorbents are mostly microporous, high specific surface materials (200 – 2000 m2/g) Most commonly used: Alumina (drying) Silicagel (drying) Zeolite molecular sieves (gas & liquid separations, drying)
WebAdsorption can be used to treat waste streams or purify valuable components of a feed. This article describes both equilibrium and mass-transfer considerations, and reviews the fundamentals of adsorption system design. Adsorption takes advantage of the tendency of one or more components of a liquid or gas to collect on the surface of a solid.
