adsorbeeritumise

Adsorbeeritumise refers to the process by which molecules of a substance, known as the adsorbate, adhere to the surface of another substance, the adsorbent. This phenomenon is a surface process, meaning it occurs at the interface between two phases, typically a solid and a gas or liquid. Unlike absorption, where molecules penetrate the bulk of the material, adsorption involves the accumulation of adsorbates only on the external or internal surfaces of the adsorbent.

The forces involved in adsorption can be physical (physisorption) or chemical (chemisorption). Physisorption is a weaker interaction driven by van der Waals forces and is reversible. Chemisorption, on the other hand, involves the formation of chemical bonds between the adsorbate and adsorbent, making it a stronger and often irreversible process. The extent of adsorption is influenced by factors such as temperature, pressure (for gases), concentration (for liquids), and the nature of both the adsorbate and the adsorbent, including its surface area and porosity.

Adsorbeeritumise has numerous practical applications. It is utilized in gas purification, such as removing pollutants from air or separating gas mixtures. In water treatment, it helps remove dissolved organic matter and heavy metals. Adsorption also plays a role in chromatography, catalysis, and even in the functioning of activated charcoal in filters and respirators. The efficiency of an adsorbent is often measured by its adsorption capacity, which is the maximum amount of adsorbate it can hold under specific conditions.
