摘　　要：面对重金属离子污染问题,开发快速且准确的重金属离子检测器具有重要意义,碳纳米材料因其易修饰、灵敏度高,常用于电化学检测重金属。此外,碳纳米材料还具有高稳定性、使用寿命长等优点,同时也存在形貌调控困难、传感效率低等问题。通常对碳材料进行官能团修饰或与其他材料复合等,加强其作为电化学传感器的传感效果。依据当前研究现状,主要介绍不同形貌碳纳米材料,如碳纳米管、碳纳米片、石墨烯等,以及其复合材料对重金属离子检测的研究前沿和动态。最后,对碳基纳米材料电化学检测重金属进行展望。Facing the problem of heavy metal ion pollution,it is important to develop rapid and accurate heavy metal ion detectors.Carbon nanomaterials are commonly used for electrochemical detection of heavy metals because of their easy modification and high sensitivity.In addition,carbon nanomaterials have the advantages of high stability and long service life,but they also have the problems of difficult morphology regulation and low sensing efficiency.Carbon materials are usually modified with functional groups or compounded with other materials to enhance their sensing effect as electrochemical sensors.Based on the current research status,the research frontiers and dynamics of different morphological carbon nanomaterials,such as carbon nanotubes,carbon nanosheets and graphene,and their composites for heavy metal ion detection are mainly introduced.Finally,an prospect on the electrochemical detection of heavy metals by carbon-based nanomaterials is presented.
