The dynamic production and usage of pharmaceuticals, mainly painkillers, indicates the growing problem of environmental contamination. Therefore, the monitoring of pharmaceutical concentrations in environmental samples, mostly aquatic, is necessary. This article focuses on applying screen-printed voltammetric sensors for the voltammetric determination of painkillers residues, including non-steroidal anti-inflammatory drugs, paracetamol, and tramadol in environmental water samples. The main advantages of these electrodes are simplicity, reliability, portability, small instrumental setups comprising the three electrodes, and modest cost. Moreover, the electroconductivity, catalytic activity, and surface area can be easily improved by modifying the electrode surface with carbon nanomaterials, polymer films, or electrochemical activation.

药品（主要是止痛药）的动态生产和使用表明了环境污染问题日益严重。因此，有必要监测环境样品（主要是水样）中的药物浓度。本文主要关注应用丝网印刷伏安传感器对环境水样中的止痛药残留（包括非甾体抗炎药、扑热息痛和曲马多）进行伏安法定量。这些电极的主要优点是简单、可靠、便携、仪器设置小巧，仅包含三个电极，成本适中。此外，通过用碳纳米材料、聚合物薄膜或电化学激活来修饰电极表面，可轻松提高电极的导电性、催化活性和表面积。
