adsorbent material
Học thuậtThân thiện
Definition
Noun: A solid substance that has the ability to attract and hold molecules of another substance (a gas or liquid) onto its surface. This process is called adsorption, which is a surface-based phenomenon distinct from absorption (where a substance is taken in throughout the entire volume).
Usage
This term is used in scientific, industrial, and technical contexts to describe materials used for purification, separation, or chemical processes. * Activated charcoal is a common adsorbent material used in water filters. * The laboratory used a special adsorbent material to remove impurities from the gas stream. * Silica gel packets contain an adsorbent material that controls humidity.
Advanced Usage
- Regeneration: Many industrial adsorbent materials, like zeolites, can be regenerated (have the captured substance removed) by applying heat or reducing pressure, allowing them to be reused.
- Selectivity: An adsorbent material can be chosen for its selective affinity, meaning it adsorbs specific target molecules from a mixture more strongly than others.
Variants and Related Words
- Adsorbent (Adjective/Noun): The property of being able to adsorb, or a shorter form for "adsorbent material".
- Adjective: Charcoal is highly adsorbent.
- Noun: We need a new adsorbent for this reaction.
- Adsorption (Noun): The process by which an adsorbent material works.
- The adsorption of pollutants onto the filter media was highly efficient.
- Adsorptive (Adjective): Relating to or having the capacity for adsorption.
- The material's adsorptive capacity was measured.
Synonyms
- Sorbent (a broader term that includes both adsorbents and absorbents)

Antonyms
- Desorbent (a material or agent that causes release of an adsorbed substance)
- Non-adsorbent material
