Asorbent is aninsoluble material that eitherabsorbs oradsorbs liquids[1] or gases.[2] They are frequently used to removepollutants and in the cleanup ofchemical accidents[3] andoil spills.[4] Besides their uses in industry, sorbents are used in commercial products such asdiapers[5] andodor absorbents,[6] and are researched for applications in environmental air analysis, particularly in the analysis ofvolatile organic compounds.[7] The namesorbent is derived fromsorption,[8] which is itself a derivation from adsorption and absorption.[9]
Sorbents collect specific liquids or gases depending on the composition of the material being used in the sorbent. Some of the most common sorbents used to clean oil spills are made from materials that are botholeophilic andhydrophobic, have high surface area through structural designs that includepores and capillaries, and draw in liquid throughcapillary action.[1] Sorbents may be used to collect undesirableions and act like a reusableion-exchange resin, composed of charged layers of material that can be heated or otherwise treated to remove pollutants.[10] In this and similar cases, pollutant particles are attracted to the sorbent throughelectrostatic forces.[11] Some sorbents chemically bind to particles through chemical adsorption, orchemisorption; this process is often more difficult toreverse.[12]
