摘要

在这篇文章中，我们介绍了一种用于水对乙酰氨基酚（ACT）检测的自校准电化学传感器。该传感器建立在石墨铅笔芯（GPL）电极上，用分子印迹聚合物（MIP）修饰，以确保选择性。此外，采用稀疏识别方案，传感器配备了动态校准算法，以提高传感器在时变测量中的精度。以自来水中制备的ACT溶液为基体，在静态和动态条件下对传感器的性能进行了评价。结果，该传感器达到了9.3 mg/L的检测限，证明是量化水中新出现的问题的可行替代方案。最后，我们展示了简单但鲁棒的传感器模型如何提高在线测量的性能。

Electrochemical Sensor With Dynamic Self-Calibration for Acetaminophen Detection in Water

In this letter, we introduce a self-calibrating electrochemical sensor for water acetaminophen (ACT) detection. The sensor is built upon a graphite pencil lead (GPL) electrode modified with a molecularly imprinted polymer (MIP) to ensure selectivity. Moreover, using a sparse identification scheme, the sensor is equipped with a dynamic calibration algorithm to increase the sensor accuracy in time-dependent measurements. The sensor performance was evaluated under static and dynamic conditions using ACT solutions prepared in tap water as the matrix. As a result, the sensor achieved a detection limit of 9.3 mg/L, proving to be a viable alternative for quantifying emerging concerns in water. Finally, we show how simple but robust sensor models could enhance the performance of online measurements.
