Definition
- Noun:
- A material that sorbs: A substance that has the property of taking up and holding another substance, either by absorbing it (taking it in throughout its volume) or adsorbing it (accumulating it on its surface).
Usage
- The word "sorbent" is a technical term used primarily in chemistry, environmental science, and engineering. It refers to the material itself that performs the action of sorption.
- It is often modified by the type of substance it captures (e.g., , ) or the mechanism (e.g., , ).
Examples
- Activated charcoal is a highly effective sorbent for many toxins and impurities.
- The spill was contained using hydrophobic sorbent booms that repelled water but soaked up the oil.
- In the laboratory, a silica gel sorbent is placed in the desiccator to keep the environment dry.
Advanced Usage
- Sorbent bed/trap: A contained volume or column filled with sorbent material used to capture specific compounds from a gas or liquid stream, often for analysis or purification.
- The air sample was drawn through a sorbent trap to collect volatile organic compounds for later analysis.
Variants and Related Words
- Sorption (n): The general process or action of a sorbent taking up another substance; the combined term for absorption and adsorption.
- Adsorbent (n): A specific type of sorbent that primarily works by adsorption (surface accumulation).
- Absorbent (n): A specific type of sorbent that primarily works by absorption (taking in throughout its bulk).
Synonyms
- Absorbent (when referring to absorption)
- Adsorbent (when referring to adsorption)
- Collector (in a general scientific context)
- Scavenger (in some chemical contexts)
Antonyms
- Desorbent (a material that releases a sorbed substance)
- Inert material (a material that does not interact with or take up other substances)
Noun
- a material that sorbs another substance; i.e. that has the capacity or tendency to take it up by either absorption or adsorption
