Abstract—This paper presents a comparative evaluation of
two activated carbons produced from different lignocellulosic
residues (spent coffee grounds and Raphanus Sativus press cake),
as adsorbents for removal of phenol from aqueous solutions in
fixed-bed column studies. Both the prepared adsorbents
presented outstanding adsorption capacities when compared to
other low-cost adsorbents presented in the literature.
Breakthrough curves were produced and several breakthrough
models were evaluated for adequate description of the
adsorption process in the column, with the Dose-Response model
presenting the best fit to the experimental data.
Index Terms—Adsorption, agricultural residues, fixed bed,
phenol removal.
