Kinetic, equilibrium and thermodynamic studies of the adsorption of paracetamol in activated carbon in batch model and fixed-bed column

Abstract This work studied the removal of paracetamol through adsorption process using granular activated carbon. The results indicated that it was possible to obtain 95% under experimental conditions pH 6, 120 min and 5 g L ?1 solid adsorbent. kinetic model best fit data pseudo-first order. isotherm Sips. thermodynamic tests favorable spontaneous confirmed endothermic nature process. In fixed bed column adsorption, operating condition found obtained flow rate 3 mL mass equal 0.5 g. this case, system presented highest volume treated PAR effluent, 810 per gram carbon in bed, besides a longer rupture time saturation.
