Abstract

The electrochemical behavior of Ag|AgCl electrode for chloride detection is closely related to the microstructure of AgCl film on the electrode surface. In this study, the surface properties and electrochemical behavior of Ag|AgCl electrode prepared with different current density were investigated. With a higher current density, the distance for ions diffusion through the boundaries of AgCl grains was reduced, due to the tended growth of AgCl at crystal plane (111) and formation of more spherical AgCl grains and porous AgCl film. As a result, both the electrical resistivity of AgCl film and Rct of Ag|AgCl electrode decreased.
