ABSTRACT Backround: The removal of pollutants by adsorption on activated carbon is widely used. However, in the presence of several pollunates at once, this elimination can be influenced. Objective: The objective of this work is the estimation of activated carbon performance when in contact with several solutes. Methods: Thus, the elimination of pyromellitic acid was carried out on an activated carbon, in the presence of 0.2 or 0.5 mmol / l of benzoic acid to the concentrations. Results: The results show that the adsorption follows the model of Freundlich. The adsorbed amounts of pyromellitic acid are slightly reduced by the presence of benzoic acid in low concentrations. However, high concentrations strongly disfavour the adsorption of acidic examined. Conclusion: The study of competitive adsorption is essential to get closer to real effluents. Keywords: Competitive adsorption, activated carbon, pyromellitic acid, benzoic acid.
