      다국어 초록 (Multilingual Abstract)

      The adsorption characteristics of phenols by the surface-modified activated carbon fibers from its aqueous solution was examined. Cellulose activated carbon fiber(toyobo Co. KF-1500) was used as an adsorbent, and it was treated with heat, air and helium. Pore-size distribution, BET surface area and surfce acidity were measured. The adsorption isotherms were found to conform with the Freundlich equation and its k values were ranged from 1.5381 to 3.6076 mmol/ g and its 1/ n values were ranged from 0.1798 to 0.3144.
      The affinity of each adsorbate on activated carbon fiber increased in the order ; Phenol <PCP<PNP. The adsorption capacity decreased when oxidized carbon was used, while it increased when redused carbon was used. The adsorption capacity increased when its surface area increased. It is concluded that the adsorption capacity changes in relation with the surface oxides and the surface area of the activated carbon fiber.
