摘要：

Adsorption and desorption of phenol on activated carbon and strong base anion-exchange resin were investigated in a fixed-bed column. Phenol was effectively adsorbed on both adsorbents. Experimental breakthrough curves were compared with values calculated on the assumption of surface diffusion controlling. Two methods of regeneration of adsorbents were carried out, that is, caustic desorption and acid desorption. Regeneration by sodium hydroxide or hydrochloric acid was effectively performed for the resin. On the other hand, regeneration of the activated carbon by sodium hydroxide was not performed completely. The adsorption capacity for activated carbon decreased grdually during the repetition process of adsorption and desorption, while the capacity for anion-exchange resin remained constant.
