摘要: 制备了NH2-UiO66和电化学还原氧化石墨烯(rGO)的混合材料NH2-UiO66/rGO,并将其成功地用于电化学同时检测镉离子(Cd2+)和铅离子(Pb2+)。通过采用扫描电子显微镜(SEM)、X射线衍射和各种电化学技术对材料的形貌及其电化学性质进行了表征。结果表明:NH2-UiO66/rGO具有较NH2-UiO66明显改善的电化学性质。所构建的电化学传感平台在优化条件下可以实现对Cd2+和Pb2+的灵敏检测。此外,该传感器具有良好的选择性、重现性和稳定性,在实际样品检测中也具有广阔的应用前景。

Abstract: In this paper, a mixed material of NH2-UiO66 and electrochemically reduced graphene oxide (rGO), NH2-UiO66/rGO, was prepared, and has been successfully used in the electrochemical determination of cadmium ions (Cd2+) and lead ions (Pb2+). The morphology and electrochemical properties of the material were characterized by scanning electron microscopy (SEM), X-ray diffraction and various electrochemical techniques. The results show that the electrochemical properties of the NH2-UiO66/rGO have significantly improved than NH2-UiO66. The constructed electrochemical sensing platform can realize the sensitive detection of Cd2+ and Pb2+ under optimized conditions. In addition, the sensor has good selectivity, reproducibility and stability, and has broad application prospects in actual sample detection.
