摘要：

The direct electrochemical oxidation and detection of hydrazine in phosphate buffer (pH 7.0) were investigated on a boron doped diamond (BDD) electrode using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. The experimental results demonstrated that a one electron transfer process was the rate-limiting step and the overall number of electrons involved in the direct electrochemical oxidation of hydrazine was four. In addition, on the proposed BDD electrode, hydrazine could be well determined by the DPV technique. The peak current linearly depended on the concentration of hydrazine in the range of 0.002-4.0 mM, and the detection limit was 1 mu M. The approach proposed here might be a potential method for the determination of hydrazine.
