Absorption vs. Adsorption: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Published on November 10, 2023
Absorption is the process where a substance permeates another; adsorption is where a substance gathers on the surface of another.
Difference Between Absorption and Adsorption
Absorption relates to the penetration of a substance into the bulk of another material, like a sponge absorbing water. On the other hand, adsorption involves the accumulation of a substance on the surface of another material, such as gas molecules sticking to the surface of a solid.

Absorption can be visualized as the process where one substance is taken up fully by another, much like how our digestive system absorbs nutrients from food. Adsorption, in contrast, is more of a surface phenomenon, like how a charcoal filter adsorbs impurities from water or air.

In absorption, the molecules are taken up by the volume of the absorbing material. For instance, when water is absorbed by a cloth, it spreads throughout its volume. In adsorption, molecules only bind to the available surface, like pollutants adhering to a mask's surface fibers.

To further clarify, imagine spilling a liquid on a table. If the table soaks up the liquid, that's absorption. If the liquid merely spreads across the table's surface, that's a simple analogy for adsorption.

Another differentiation between absorption and adsorption can be seen in their applications. Absorption is crucial in areas like nutrition and drug delivery, where substances need to be assimilated into the system. Adsorption is vital in processes like water purification, where contaminants are removed by adhering them to surfaces.
