Carbamazepine (CBZ) is a pharmaceutical compound used in medical practice. Due to the ecotoxicological risk of its presence in the aqueous environment, researchers have been investigating its removal by adsorption technique. The aim of this study is to review the works done on the removal of CBZ from water by adsorption. Carbon-based materials were the best types of adsorbent for CBZ uptake (> 200 mg g−1). Molecularly imprinted polymer (MIP) and carbon nanotubes (CNTs) showed especially good adsorption capacities. The key mechanisms of CBZ adsorption were π-π interaction, electrostatic interactions, hydrogen-bonding and hydrophobic interactions. Classical equilibrium isotherm models like Langmuir and Freundlich were always best-fits and kinetics modelling was best-fit to the pseudo-second order model. The thermodynamics modelling of CBZ adsorption showed it was spontaneous and endothermic for most adsorbents. Methanol and acetone were especially effective for the desorption of CBZ from adsorbents and can achieve > 90 % removal even after 4–5 cycles. CBZ competes favorably in adsorption systems with other pharmaceutical species due to the advantages of the hydrophobic effect and molecular size.

卡马西平水相吸附的新进展
卡马西平 (CBZ) 是一种用于医疗实践的药物化合物。由于其存在于水环境中的生态毒理学风险，研究人员一直在研究通过吸附技术将其去除。本研究的目的是回顾通过吸附从水中去除 CBZ 所做的工作。碳基材料是吸收 CBZ 的最佳吸附剂类型（> 200 mg g -1）。分子印迹聚合物 (MIP) 和碳纳米管 (CNT) 表现出特别好的吸附能力。CBZ吸附的关键机制是π-π相互作用、静电相互作用、氢键和疏水相互作用。像 Langmuir 和 Freundlich 这样的经典平衡等温线模型总是最适合的，而动力学模型最适合伪二阶模型。CBZ 吸附的热力学模型表明，对于大多数吸附剂来说，它是自发吸热的。甲醇和丙酮对 CBZ 从吸附剂上的解吸特别有效，即使在 4-5 个循环后也能达到 > 90% 的去除率。由于疏水效应和分子大小的优势，CBZ 在吸附系统中与其他药物种类竞争激烈。
