[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 m2/g or more or a surface oxide amount of 0.20 meq/g or less, or alternatively, a BET specific surface area of 800 m2/g or more and a surface oxide amount of 0.50 meq/g or less, and wherein a sum (Vmic) of a volume of micropores of 1 nm or less of the activated carbon adsorbent is 0.30 cm3/g or more.
