From voltammetric experiments, the electrochemical behavior of piperazine (PPZ) was determined at gold electrode (GE) in pH 7, 0.2 M phosphate buffer solution. It is shown that in the presence of PPZ the electrochemical oxidation at a GE was irreversible process. Based on the experimental results suitable mechanism was proposed. The electrooxidation of PPZ showed diffusion controlled. Under optimized conditions, linearity between the peak current and PPZ concentration was observed in the range of 1.0x10-6–1.7x10-5 M and LOD was found to be 4.49 x 10-8 M. Further, the sensor was used for the assay of PPZ in biological samples.
