In order to solve the problem that the traditional heavy metal ions detection method cannot meet the emergency de- tection, and realize online detection of heavy metal ions in water environment, a combined eletrochemical metal quality detection method is put forward. The working principles of ion selective electrode method and anodic stripping voltammetry are analyzed. The structure of the heavy metal ions in water environment on-line dection system is constructed, and system testing software work flow is designed. The detection and analysis test are conducted, the experimental results show that the detection unit based on integrated type electrochemical water quality detection method work stably, which meets the requirement of system.
