Batch and Column Studies of Phenol Adsorption by an Activated Carbon Based on Acid Treatment of Corn Cobs

Pablo D. Rocha, Adriana S. Franca, and Leandro S. Oliveira
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.
