Desorption

Desorption is the process of removing a substance from the surface of a solid or liquid when heated or cooled, or as a result of a change in the chemical composition of the medium. This process occurs when a substance that was adsorbed on a surface loses its connection with it and turns into a gaseous or liquid state.

Desorption can be observed in many processes, such as the evaporation of liquids, desorption of gases from adsorbents, and desorption of solids from solutions. An example of desorption is the process of purifying gases from harmful impurities by adsorption on special sorbents, and then desorption of these impurities when heated.

The desorption process is of great importance in various fields of science and technology, such as chemistry, physics, biology and medicine. It is used to purify air, water and other liquids from harmful substances, to isolate and purify various compounds, to analyze biological samples, etc.

In order to speed up the desorption process, various methods can be used, such as heating, changing pressure, adding solvents and others. However, when using these methods, it is necessary to take into account that some substances may be sensitive to changes in desorption conditions and may be destroyed or change their properties.

In general, desorption is an important process that has wide applications in various fields of science and technology. It allows you to purify, analyze and isolate various substances from mixtures and solutions, as well as create new materials and compounds.
