Commercial activated carbons NORIT SA2 and&nbsp; two&nbsp; granulations&nbsp; of&nbsp; DARCO&nbsp; were&nbsp; used.&nbsp; Activated carbons&nbsp; were&nbsp; characterized&nbsp; using&nbsp; FTIR&nbsp; spectroscopy, SEM&nbsp; analysis,&nbsp; internal&nbsp; surface&nbsp; analysis&nbsp; using&nbsp; nitrogen adsorption&nbsp; on&nbsp; low&nbsp; temperature&nbsp; and&nbsp; determination&nbsp; of point&nbsp; of&nbsp; zero&nbsp; charge.&nbsp; Geometry&nbsp; optimization&nbsp; of nitrophenol&nbsp; and&nbsp; amide&nbsp; molecules&nbsp; has&nbsp; been&nbsp; carried&nbsp; out and different molecular parameters have been calculated. Influence&nbsp; of&nbsp; amides&nbsp; as&nbsp; AOM&nbsp; model&nbsp; has&nbsp; been investigated by using diffusion and equilibrium models. Biot number has been obtained&nbsp; in order to establish the limiting&nbsp; step&nbsp; in&nbsp; adsorption&nbsp; process.&nbsp;&nbsp; Adsorption parameters&nbsp; obtained&nbsp; in&nbsp; two-component&nbsp; adsorption systems&nbsp; were&nbsp; compared&nbsp; to&nbsp; parameters&nbsp; obtained&nbsp; for adsorption of nitrophenols alone.</p>
