Abstract: Lead ion commonly exists in air,water,soil and food,and in which the concentration of lead is increasing. Lead ion is a toxic pollutant and is extremely harmful to human health. A lot of strategies have been proposed for detecting lead ion,carbon-based electrochemical sensors have gained growingly attentions owing to simplicity,rapidity and sensitivity. From the point of view of modified material of composite electrode,this paper reviews the research progress of composite electrodes based on inorganic materials,organic materials and functional nucleic acids in the detection of lead ion. The development,construction approaches and sensing performances of carbon-based electrodes are mainly introduced. At last,the trends of the carbon-based lead-ion electrochemical sensor are also prospected.
