Abstract: The stability of the chloride ion selective electrode in highly alkaline solutions must be ensured; otherwise, the application in concrete is not feasible. A simple solution to this problem is to increase the amount of compact and uniform AgCl film on Ag wire by adjusting the current density and anodizing time. In this study the Ag/AgCl electrodes were prepared in four different current densities and the microstructures of the electrodes were compared and the potentiometric response of the electrodes to chloride in water, synthetic concrete pore solution and cement extracted solution was systematically studied.
