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...

The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitude—i.e., the maximum displacement or movement of a point on the wave—and, as the wave passes through a substance, its amplitude ...

Absorption band: An absorption band is defined as a distinct region in the electromagnetic spectrum where a substance specifically absorbs a “given wavelength” of light due to its specific interactions with its atoms/molecules. The study and interpretation of absorption bands play a crucial role in various spectroscopic techniques like UV ...

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.
