[SUMMARY] [OBJECT] To provide a per- and polyfluoroalkyl compound-adsorbing activated carbon having a high collection rate of per- and polyfluoroalkyl compounds in an atmospheric sample, and a filter body using the same. [ACHIEVING MEANS] A per- and polyfluoroalkyl compound-adsorbing activated carbon for desorbably adsorbing per- and polyfluoroalkyl compounds in an atmospheric sample, the activated carbon including an activated carbon adsorbent having a BET specific surface area of 900 m/g or more, a sum (V) of a volume of micropores of 1 nm or less of 0.35 cm/g or more, a sum (V) of a volume of mesopores of 2 to 60 nm of 0.02 cm/g or more, a volume difference (V) between the micropore volume (V) and the mesopore volume (V) of 0.45 or more, and a surface oxide amount of 0.10 meq/g or more.

Per- and polyfluoroalkyl compound-adsorbing activated carbon

[OBJECT] To provide an activated carbon for adsorbing per- and polyfluoroalkyl compounds in a water sample, the activated carbon having a high collection rate of per- and polyfluoroalkyl compounds in a water sample, and a filter body using the same. [ACHIEVING MEANS] An activated carbon for adsorbing per- and polyfluoroalkyl compounds in a water sample to desorbably adsorb per- and polyfluoroalkyl compounds in a water sample, wherein the activated carbon is composed of an activated carbon adsorbent having a BET specific surface area of 800 m/g or more or a surface oxide amount of 0.20 meq/g or less, or alternatively, a BET specific surface area of 800 m/g or more and a surface oxide amount of 0.50 meq/g or less, and wherein a sum (V) of a volume of micropores of 1 nm or less of the activated carbon adsorbent is 0.30 cm/g or more.
