{{Short description|Material that absorbs or adsorbs}}{{More citations needed|date=December 2009}}(File:Cross section of filter of gas mask.jpg|thumb|300px|Cross-section of a gas mask filter, with sorbent material visible)A sorbent is a material that either absorbs or adsorbs liquids or gases.WEB, Definition of 'sorbent',weblink collinsdictionary, HarperCollins Publishers, - the content below is remote from Wikipedia

Examples
Sorbents come in various forms and materials, including:- Similar to molecular sieve material, a sorbent may function via adsorption, attracting molecules to its surface. These are typically supplied in pellets (1mm to 2mm diameter, approximately 5mm length) or grains (~1mm), occasionally as beads up to 5mm in diameter, and are commonly made from aluminium oxide featuring a porous structure.
- Materials with a high affinity for absorbing other materials, such as:
- Dry, high-carbon materials used in composting to absorb odoriferous chemicals, which assist in decomposing the sorbents.
- Sponges, which can absorb many times their own weight in water.
- Polypropylene fiber mats, which can be employed to absorb oil.
- Cellulose fiber products used for oil absorption.
- The granular gel material in baby diapers, capable of absorbing multiple times its original weight in urine.
- Desiccants, which attract water, thereby drying (desiccating) surrounding materials.
Method of action
{{Confusing section|date=October 2022}}In instances of chemical spills where sorbents are utilized, oil-absorbent pads should exhibit oleophilic (oil-attracting) and hydrophobic (water-repelling) properties. Sorbent materials operate primarily through adsorption, and less frequently, by absorption. Both mechanisms involve the incorporation of the oil or another liquid into the material's structure, though the methods of incorporation differ.WEB, 2021-06-29, What are Oil Absorbent Pads Made Of?
