Title:
NEUTRAL PER AND POLY-FLUOROALKYL COMPOUND-ADSORBING ACTIVE CARBON, AND ANALYTIC METHOD OF NEUTRAL PEL AND POLY-FLUOROALKYL COMPOUND IN WATER SAMPLE
Document Type and Number:
Japanese Patent JP2022057196
Kind Code:
A
Abstract:
To provide a neutral per and poly-fluoroalkyl compound-adsorbing active carbon which is an active carbon to be used for a quantitative analysis of a neutral per and poly-fluoroalkyl compound in a water sample, and can detachably collect a neutral per and poly-fluoroalkyl compound.SOLUTION: A neutral per and poly-fluoroalkyl compound-adsorbing active carbon as an active carbon to be used for a quantitative analysis of a neutral per and poly-fluoroalkyl compound in a water sample comprises an active carbon in which a BET specific surface area for detachably absorbing a neutral per and poly-fluoroalkyl compound distributed in a gas phase from the water sample due to that inactive gas as carrier gas is ventilated or bubbled, in the water sample sealed in a container and adjusted in a temperature at which a neutral per and poly-fluoroalkyl compound can be distributed in a gas phase is 900 m2/g or more.SELECTED DRAWING: None
