adsorber
Definition
- Noun (Chemistry):
- A device or material that adsorbs: An "adsorber" is a substance or apparatus used to collect molecules of a gas or liquid onto its surface through the process of adsorption (where atoms, ions, or molecules adhere to a surface). Unlike absorption, adsorption involves surface attachment rather than penetration into the bulk material.
Usage Examples
- Noun:
- The laboratory uses a carbon adsorber to remove volatile organic compounds from the air. (A device containing activated carbon that captures pollutants by surface adhesion.)
- This silica gel adsorber effectively traps moisture in electronic equipment. (A material that attracts and holds water vapor on its surface.)
Advanced Usage
"Activated carbon adsorber": A common type of adsorber used in water purification and air filtration.
- The activated carbon adsorber in the filter removes chlorine and odors from tap water. (The carbon-based device adsorbs impurities.)
"Thermal swing adsorber": An adsorber that uses temperature changes to release captured substances for regeneration.
- The thermal swing adsorber heats up to desorb the collected gases, allowing the adsorbent to be reused. (The device cycles between adsorption and desorption by varying temperature.)
Variants and Related Words

- The charcoal will adsorb the toxic gases. (The charcoal attracts and holds gas molecules on its surface.)
Adsorption (noun): the process of molecules adhering to a surface.
- Adsorption occurs when the gas molecules stick to the solid adsorbent. (The adhesion process.)
Adsorbent (noun/adjective): a material that adsorbs other substances.
