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

这项工作研究了使用颗粒状活性炭通过吸附过程去除扑热息痛的方法。结果表明，在pH 6、120分钟工艺和5 g L ^-1固体吸附剂的实验条件下，可以获得95％的去除率。最适合实验数据的动力学模型是伪一阶。最适合实验数据的等温线模型是Sips。热力学测试表明吸附过程是有利的和自发的，并证实了该过程的吸热性质。在固定床色谱柱吸附中，使用3 mL min ^-1的流速可获得最佳的运行条件床质量等于0.5克。在这种情况下，除了破裂时间和床饱和时间更长之外，该系统处理后的PAR流出量最高，为每克床中810毫升碳。
