ACTIVE CARBON FIBER FOR REMOVING MALODOROUS GAS AND AIR CLEANING SHEET

摘要

PROBLEM TO BE SOLVED: To provide an active carbon fiber for removing malodorous gases which has a high capacity of removing lower aldehydes and basic gases and a high rate of removing such gases and to provide an air cleaning sheet using the same. SOLUTION: There is provided an active carbon fiber carrying an aromatic amino acid salt and phosphoric acid, wherein the amount of the aromatic amino acid salt carried is 7-30 mass %, the amount of the phosphoric acid carried is such that the ratio of the number of moles of the phosphoric acid carried to the number of moles of the aromatic amino acid salt carried is 0.05-1.0, and the specific surface area of the active carbon fiber carrying them is 300-1,000 m2/g.
