Pharmaceutical pollutants are of significant effect on the environment, so that their treatments have been addressed in many studies. Activated carbon (AC) adsorbent shows best attraction for these compounds due to its unique characteristics represented by high capacity and porosity. In this article, the adsorption performance of AC towards non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, ketoprofen, naproxen, and diclofenac were reviewed. According to collected data, maximum adsorption capacities of 417, 25, 290, and 372 mg/g were obtained from Langmuir isotherm for these drugs, respectively. The values of 1/n for Freundlich isotherm were lower than unity for all studied drugs, confirming the nonlinear and favorable adsorption. In addition, kinetics data were well represented by the pseudo-second-order model and mechanism was not controlled by the pore diffusion step alone. AC adsorption demonstrated superior performance for all selected NSAIDs, thus being efficient technology for treatment of these pharmaceutical pollutants.
药物污染物对环境有重大影响，因此许多研究都探讨了它们的处理方法。活性炭（AC）吸附剂因其高容量和孔隙率等独特特性，对这些化合物表现出最佳的吸附能力。本文综述了AC对布洛芬、酮洛芬、萘普生和双氯芬酸等非甾体抗炎药（NSAIDs）的吸附性能。根据收集的数据，通过朗缪尔等温线分别得出这些药物的最大吸附容量为417、25、290和372 mg/g。对于所有研究的药物，弗伦德里希等温线的1/n值均低于1，证实了非线性和有利的吸附。此外，动力学数据能用准二级模型很好地表示，且吸附机理并非仅由孔扩散步骤控制。AC吸附对所有选定的NSAIDs均表现出优异性能，因此是处理这些药物污染物的有效技术。
