WebDec 28, 2024 · Adsorption is one of the best techniques for decontamination of water and air systems, due to its low cost, ease of operation, minimal waste disposal, and environment friendliness. It has... Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate (solute )* on the surface of the adsorbent(solvent). This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent). Adsorption is a surface phenomenon and does not penetrate throu…
WebSep 16, 2024 · All surface sites have the same adsorption energy for the adsorbate. The adsorbate is usually argon, krypton or nitrogen gas. The surface site is defined as the area on the sample where one molecule of the gas can adsorb onto. Adsorption of the solvent at one site occurs independently of adsorption at the neighbouring sites.
