摘要： An activated carbon for adsorbing neutral per- and polyfluoroalkyl compounds used in quantitative analysis of neutral per- and polyfluoroalkyl compounds in a water sample includes an activated carbon having a BET specific surface area of 900 m2/g or more for desorbably adsorbing neutral per- and polyfluoroalkyl compounds distributed in a gas phase from the water sample by aerating or bubbling, with an inert gas as a carrier gas, the water sample sealed in a vessel and temperature-controlled to a temperature at which the neutral per- and polyfluoroalkyl compounds can be distributed in a gas phase.
