A novel super-thin carbon paste film electrode was introduced as a silver ion sensor.The electrode was prepared by inlaying carbon paste onto the surface of nickel-chromium substrate.The electrode response characteristics were investigated by potentiometry.The calibration curve of the electrode shows a linear potentiometric response to Ag+ in the range of 10-6～10-2 mol/L with a slope of 58.3～60.3 mV/(-logcAg+).The limit of detection is 6.0×10-7 mol/L.The electrode described in this paper is very simple, stable and unexpensive.It was used as an indicator electrode for the determination of Ag+.

Key words: super-thin carbon paste film electrode, sensor, inlaid electrode
