摘要：

The kinetics of adsorption of five aromatic compounds in aqueous solution was studied in a batch system using activated carbons from eucalyptus kraft lignin as adsorbents. The batch adsorption processes were carried out in a range of temperatures; the values for the experimental variables were selected from previous tests. The rate and the adsorption yield were the main output information. The extent of adsorption is reported as plots of the adsorbate concentration on the solid phase versus time; an empirical equation has been applied for the experimental kinetic data fittings. The apparent mass-transfer order has been determined by applying a pseudo-nth-order rate equation. In addition, effective intraparticle diffusion coefficients have been estimated for all the studied cases.
