Abstract—Corn cobs were evaluated as raw material in the
production of an adsorbent for phenol removal from aqueous
solutions. Adsorption kinetics and equilibrium were
satisfactorily described by the pseudo second-order and
Freundlich models, respectively. Fixed bed adsorption
(breakthrough curve) was satisfactorily described by
Bohart-Adams, Yoon-Nelson and Dose-Response models.
Adsorption tests showed that the prepared adsorbent presented
higher adsorption capacity than activated carbons produced
from other agricultural residues, confirming that this type of
waste material is a suitable candidate for use in the production
of adsorbents.
Index Terms—Adsorption, agricultural residues, corn cobs,
phenol removal.
