The adsorption of dibenzofuran(DBF)on three commercial granular activated carbons(GAC)was in- vestigated to correlate the adsorption equilibrium and kinetics with the morphological characteristics of activated carbons.Breakthrough experiment was conducted to determine the isotherm and kinetics of dibenzofuran on the ac- tivated carbons.All the experiment runs were performed in a fixed bed with a process temperature of 368 K.The effects of adsorbent morphological properties on the kinetics of the adsorption process were studied.The equilib- rium data are found satisfactory fitted to the Langmuir isotherm.An intraparticle diffusion model based on the ob- tained Langmuir isotherm was developed for predicting the fixed bed adsorption of dibenzofuran.The result indi- cated that this model fit all the breakthrough curves well.The surface diffusion coefficients of dibenzofuran on the activated carbon are calculated,and a relationship with the microporosity is found.As it was expected,the diben- zofuran molecule finds more kinetic restrictions for the diffusion in those carbons with narrower pore diameter.
