material which can adsorb a chemical or contaminant out of solution (Hoehn, 1996).
The material which adsorbs i.e. the solid which attracts and holds on its surface the gas, vapour or liquid. Also materials added to liquors to decolourise or purify by adsorbing the colour or impurity. Fullers earth, activated carbon, activated alumina, etc, are all adsorbents
Material that is capable of the binding and collection of substances or particles on its surface without chemically altering them.
The process in which matter adheres to the surface of an adsorbent.
The substrate material onto which a substance is adsorbed.
Material on whose surface adsorption takes place.
a material having capacity or tendency to adsorb another substance
having capacity or tendency to adsorb or cause to accumulate on a surface
a substance that causes passing molecules or ions to adhere to its surface
a substance that has the ability to condense or hold molecules of other substances on its surface and/or the ability to take up other substances, i
An adsorber. That upon which adsorption takes place. It is the material to which a gas molecule is attached and retained.
This is a solid substance which binds other substances to its surface but does not interact chemically with them.
A material, usually solid, capable of holding gases, liquids and/or suspended matter at its surface and in exposed pores. Activated carbon is a common adsorbent used in water treatment.
An adsorptive material; one that absorbs moisture. Important for the manufacture and preservation of formulations containing hygroscopic (“water-loving”) ingredients. Can help prolong shelf-life.
the surface of a material, where a different material is being concentrated
Compare with absorbent. A substance that collects molecules of another substance on its surface. For example, gases that make water taste bad are strongly adsorbed on activated charcoal granules in water filters.
Substance with the property to hold molecules of fluids without causing a chemical or physical damage.
Packing used in adsorption chromatography. Silica gel and alumina are the most frequently used adsorbents in HPLC.
The material (activated carbon) that is responsible for removing the undesirable substance in the adsorption process.
adsorb; or to collect as molecules or gasses; dissolved substances, or liquids, in a thin layer on the surface; as in the case of belt or disk skimmers used for the collection of floating light non-aqueous phase liquids (LNAPL) from the surface of water bodies.
A material which has the ability to cause molecules of gases, liquids, or solids to adhere to its internal surfaces without changing the adsorbent physically or chemically. Certain solid materials, such as silica gel and activated alumina, have this property.
In addition to the adjectival meaning, the term describes any of several substances that collect gaseous pollutants. Used both for measurement and control.
a substance, usually porous, that allows the molecules of a gas or liquid to adhere to its large surface area
Refers to the material often used to pack columns used in ADSORPTION CHROMATOGRAPHY, most often alumina or silica gel.
A water treatment medium, usually solid, capable of the adsorption of liquids, gases, and/or suspended matter. Activated alumina and activated carbon are common adsorbents used in water processing.
