摘　　要：污染物邻氨基苯酚(o-AP)对环境安全构成相当大的风险,因此对其进行检测至关重要。虽然已有多种光学和电化学方法用于邻氨基苯酚的检测,但基于光电化学(PEC)传感器的检测方法数量有限。本研究开发了一种灵敏的可见光驱动PEC传感器,用于检测水中的o-AP。本研究首先制备了石墨烯接枝共轭微孔聚合物的异质结构传感材料(CMP-rGO),并将其用于开发PEC传感器。在最佳实验条件下,该传感器对o-AP的灵敏度高达0.03μM,线性范围为0.0034~37.6μM。PEC传感器还具有可良好的重复性和再现性、出色的长期稳定性和良好的回收率(98%~102%)。本研究为o-AP的检测提供了一种新的、可行的基于PEC传感器的检测方案。The pollutant o-aminophenol(o-AP)presents a considerable risk to environmental safety,and its detection is therefore critical.Although various optical and electrochemical methods have been proposed for the detection of o-AP,there are limited numbers of detection methods based on photoelectrochemical(PEC)sensors.A sensitive visible-light-driven PEC sensor was developed for o-AP detection in water.A conjugated microporous polymer(CMP)-coated graphene heterostructure(CMP-rGO)was synthesized and used to develop a PEC sensor.Under optimal conditions,the proposed sensor exhibited a high sensitivity of 0.03μM with a wide linear range of 0.0034~37.6μM.The PEC sensor also displayed acceptable repeatability and reproducibility,good long-term stability and excellent recovery(98%~102%).This study provided a new and feasible PEC sensor-based detection scheme for o-AP detection.
