| Abstract: | The structure and principle of controlled potential electrochemical sensor for ozone in water are described. By integrated analysis of cyclic vohammetry curve, polarization curve and current response curve versus different Potential,it is indicated that when controlled Potential selected is 0. 50 V, the current response of the sensor is a better linearity and higher sensitivity. Moreover, the potential control circuit and signal measuring circuit are designed and applied in controlling Potential and processing the output signal of the sensor. |
