Cross-section of a gas mask filter, with sorbent material visible

A sorbent is an insoluble material that either absorbs or adsorbs liquids[1] or gases.[2] They are frequently used to remove pollutants and in the cleanup of chemical accidents[3] and oil spills.[4] Besides their uses in industry, sorbents are used in commercial products such as diapers[5] and odor absorbents,[6] and are researched for applications in environmental air analysis, particularly in the analysis of volatile organic compounds.[7] The name sorbent is derived from sorption,[8] which is itself a derivation from adsorption and absorption.[9]
