Absorption vs. Adsorption - The Engineer

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… WebIn chemistry, adsorption is the targeted transfer of particular components of a fluid phase to the surface of an insoluble solid, which is known as solubility. The adsorbed solute is known as an adsorbate, while the solid substance is known as an adsorbent. WebAdsorption is defined as the adhesion of a chemical species onto the surface of particles.
