Application progress of Ag/AgCl electrodes for electrochemical sensors.

With the application of electrochemical sensing technology in environmental detection, life science, biomedicine, food safety and other fields, the requirements for reference electrodes are also gradually increased. In this paper, the research and application progress of Ag/AgCl reference electrode are summarized from four aspects: 1) development situation of Ag/AgCl electrode; 2) preparation and application of Ag/AgCl electrode; 3) performance of charge transfer of Ag/AgCl electrode and influence of ion conduction on performance; 4) Research progress of doped modified Ag/AgCl electrode of carbon nanotubes. Ag/AgCl electrodes will remain the focus of future research due to their designability, flexibility, and excellent manufacturing properties. [ABSTRACT FROM AUTHOR]
