The recovery of benzoic acid, as an intermediate and additive component in chemical industries, is a convectional process. Also, benzoic acid is usually removed as a pollutant from wastewater streams and is treated with a fixed-bed, via physical adsorption processes, onto granular activated carbon. In this research work, wastewater is passed onto active carbon in a chromatographic glass tube and the related heat of adsorption is measured by a calorimeter. The results show that this adsorption is physical, because the amount of heat of adsorption is less than the minimum chemical adsorption. In addition, in the present research work, the bed depth effect of resin and the feed volumetric flow rate have been studied at laboratory scale to determine optimum conditions. Finally, based on experiments and their results, the optimum conditions are determined at a 6 cm bed depth with a granular carbon active resin 30-36 mesh, 0.75 ml/min volume flow rate and a chromatographic glass tube with an inner diameter of 9.5 mm.
