Adsorption Meaning: Definition, Examples, and Translations
๐งช
adsorption
[ษdหzษหrpสษn ]
Definition
science process
Adsorption is the process by which atoms, ions or molecules from a gas, liquid, or dissolved solid adhere to a surface. This surface can be solid or liquid, and the adhered material is referred to as the 'adsorbate.' Adsorption occurs at an interface and is distinguished from absorption, wherein a substance is fully integrated into another. It plays a critical role in various applications, from catalysis to environmental remediation.
Synonyms
adhesion, attachment, sticking.
Examples of usage
- The adsorption of water vapor on silica gel is a common example.
- Carbon filters rely on the adsorption of impurities to purify air.
- The efficiency of adsorption can vary based on temperature and pressure.

Origin of 'adsorption'
The term 'adsorption' is derived from the Latin prefix 'ad-' meaning 'to' or 'towards' combined with the word 'sorb', which comes from the Latin 'sorbere' meaning 'to soak up'. The distinction between adsorption and absorption was made in scientific literature in the late 19th century. Adsorption gained prominence with the advancement of physical chemistry and materials science, as it is a fundamental process in catalysis, filtration, and the study of surfaces. Its applications span diverse fields including environmental science, pharmaceuticals, and nanotechnology, underscoring its significance for understanding molecular interactions and material behaviors.
