Comparison of Microwave Assisted Thermo-Chemical Procedures in the Production of Adsorbents for Wastewater Treatment
Cibele C. O. Alves, Adriana S. Franca, and Leandro S. Oliveira
Abstract—Agricultural residues were evaluated as raw
material in the production of adsorbents for phenol removal
from aqueous solutions. A comparative evaluation of acid and
basic activating agents is presented. Adsorption kinetics and
equilibrium were satisfactorily described by the pseudo
second-order and Freundlich models, respectively. Adsorption
tests showed that the prepared adsorbents 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.
