In this work, a high porous activated carbon from Jacaranda mimosifolia was developed and employed for ketoprofen adsorption. After the pyrolysis process at 973.15 K, the material presented cavities with different sizes allocated on the particle surface. The material presented a pH at the point of zero charge of 4.1 with the best adsorption at pH 2. The best adsorbent dosage was 0.72 g L^-1, corresponding to a removal of 96%. The system reached the adsorption equilibrium after 120 min and was described by the linear driving force model. The isotherms revealed that the adsorption capacity decreased with the temperature and followed the Langmuir model, with a maximum adsorption capacity of 303.9 mg g^-1. This high capacity can be associated with the high surface area (928 m² g^-1) and pore volume (0.521 cm³ g^-1) values. The thermodynamic values indicated that the adsorption system is spontaneous and exothermic. The enthalpy value indicates that the interactions between the adsorbent and adsorbate are physical. Regeneration tests showed a decreasing percentage of removal of 7.86% after 5 cycles. Finally, the adsorbent showed efficiency when treating a simulated effluent containing drugs and inorganic salts, showing the removal of 71.43%.

在这项工作中，开发了来自蓝花car（Jacaranda mimosifolia）的高多孔活性炭，并将其用于酮洛芬的吸附。在973.15  K处进行热解后，该材料呈现出在粒子表面分配有不同尺寸的空腔。该材料在零电荷点的pH值为4.1，在pH 2时具有最佳吸附。最佳吸附剂剂量为0.72  g  L ^-1，对应去除率为96％。该系统在120 分钟后达到吸附平衡，并通过线性驱动力模型进行描述。等温线表明，吸附量随温度降低而下降，并遵循Langmuir模型，最大吸附量为303.9  mg  g ^-1。这种高容量可与高表面积（928相关联 平方米克^-1）和孔体积（0.521厘米³克^-1）值。热力学值表明吸附系统是自发的并且放热的。焓值表明吸附剂和被吸附物之间的相互作用是物理的。再生测试显示5个循环后去除率降低了7.86％。最后，吸附剂在处理含有药物和无机盐的模拟流出物时显示出效率，显示出71.43％的去除率。
