Heavy metals are difficult to biodegrade and pose a serious threat to the environment and human life and health. Hence, the detection and treatment of heavy metal pollution is vital. In recent years, electrochemical methods for the detection of heavy metal ions have become a research hotspot in the field of heavy metal detection because of their high sensitivity, fast analysis speed and the ability to detect multiple metal ions simultaneously. This paper reviews the detection principles and development status of common electrochemical detection methods, and describes the detection effects of potentiometric analysis, potentiometric stripping analysis and voltammetry by introducing the parameters of linear range, detection limit and recovery. Finally, the review outlines the advantages and disadvantages of various methods, and points out the future research directions in order to provide a basis for the application of electrochemical sensors.

Key words: Heavy metal detection, Electrochemical analysis, Potentiometric analysis, Potentiometric stripping analysis, Voltammetry
