Both of them were modified on the surface of gold electrode as the work electrode. The detection of H2O2 was studied by the method of Amperometric i-t Curve. Under the optimized experimental conditions, H2O2 could be detected in a linear calibration range of 2.0×10−5-1.0×10−3M with a correlation coefficient of 0.9950 (n=10), the detection limit was 2.0×10−6M (3σ) and the recovery ratio was 96.9-108.1%, which indicated that the accuracy of this method is excellent. The modified electrodes display excellent electrochemical performance, high sensitivity, good reproducibility, and long-term stability.
