摘要：

The desorption of phenol from activated carbon in aqueous systems is studied here at various temperatures and adsorbed concentration levels in a stirred batch system. It is found that at sufficiently rapid stirring rates the desorption is controlled by intraparticle mass transfer. The effective diffusivity value is estimated to be 2.1 x 10_lom2/s at 30°C and increases to 6.7 x 10_lom2/s at 80°C, yieldinv tortuosity values that are essentially temperature independent. © 1990, Taylor & Francis Group, LLC.
