A novel hydrogen peroxide (H2O2) potentiometric sensor, made with a MnO2-doped carbon paste electrode (CPE), is reported. Under optimum conditions, the electrode gives a Nernstian response for H2O2 in the concentration range 3.00 x 10 (- 7) -3.63 x 10 (- 4) mol/l, with a slope of 21-19.4 mV/pH(2)O(2) and a detection limit of 1.2 x 10 (- 7)mol/l H2O2. In addition, this sensor offers some analytical characteristics such as sensitivity, good reproducibility and a simple preparation procedure. The effects of both the components of the electrode and other conditions on the potential response of the sensor, as well as the possible response mechanism, are discussed.
