摘　　要：本研究旨在探讨氨基化石墨烯电化学传感器在重金属离子检测中的应用,特别是针对Cd^(2+)和Pb^(2+)的检测。研究内容主要包括氨基化石墨烯(NH_(2)-rGO)、壳聚糖(CS)和聚谷氨酸(Glu)复合材料修饰电极的制备,以及其在电化学检测中的性能评估。通过对不同修饰电极的表征与性能分析,本研究揭示了NH_(2)-rGO/CS/Glu复合材料修饰电极在提高检测灵敏度和选择性方面的显著效果。研究结果表明,相比于裸电极和单一材料修饰电极,NH_(2)-rGO/CS/Glu修饰电极对Cd^(2+)和Pb^(2+)展现出了更高的灵敏度和优异的选择性。此项研究为开发新型高效电化学传感器提供了有价值的参考,对于环境监测和重金属污染控制具有重要意义。This study aims to explore the application of amino fossil graphene electrochemical sensors in the detection of heavy metal ions,especially for the detection of Cd^(2+)and Pb^(2+).The research mainly includes the preparation of composite materials modified electrodes with amino functionalized graphene(NH_(2)-rGO),chitosan(CS),and polyglutamic acid(Glu),as well as their performance evaluation in electrochemical detection.Through the characterization and performance analysis of different modified electrodes,this study revealed the significant effect of NH_(2)-rGO/CS/Glu composite material modified electrodes in improving detection sensitivity and selectivity.The research results indicate that compared to bare electrodes and single material modified electrodes,NH_(2)-rGO/CS/Glu modified electrodes exhibit higher sensitivity and excellent selectivity towards Cd^(2+)and Pb^(2+).This study provides valuable reference for the development of new and efficient electrochemical sensors,which is of great significance for environmental monitoring and heavy metal pollution control.
