Usually, when people think about adsorption and absorption, they consider the mass transfer of liquid particles onto (adsorption) or into (absorption) solids. But, these processes can involve plasma, gases, liquids, or dissolved solidswhere the ions, atoms, or molecules are adsorbed or absorbed by liquids or solids. While both sorption processes sh...
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. The rate of the process depends largely on surface a...
Absorption occurs when ions, atoms, or molecules pass into a bulky material. These particles (the absorbate) diffuse or dissolve into the absorbent substance. A familiar example is a paper towel picking up water. Eventually, water evenly permeates the paper. Absorption occurs passively (diffusion) or actively (facilitated diffusion or active transp...

ISBN 0-534-39573-2.Chemical absorption or reactive absorption is a chemical reaction between the absorbed and the absorbing substances. Sometimes it combines with physical absorption. This type of absorption depends upon the stoichiometry of the reaction and the concentration of its reactants.
Jul 3, 2019 · Definition: Absorption is the process by which atoms, molecules, or ions enter a bulk phase (liquid, gas, solid). Absorption differs from from adsorption, since the atoms/molecules/ions are taken up by the volume, not by surface. Examples: absorption of carbon dioxide by sodium hydroxide.
