Study on Electrochemical Behavior of Hydrazine at a Glassy Copper Nanoparticles

In this study, a novel and convenient electrochemical sensor was fabricated by using dripping well-dispersed graphene oxide nanosheets, electropolymerization of poly glycine (p-Gly) and in situ plating of metallic copper na was further employed to investigate the electrochemical behavior of hydrazine. Scanning electron microscopy and energy dispersive X-ray spectrometry were used for the electrode shifts by about 150 mV toward negative values compared with that on the bare electrode. The kinetic ) and charge transfer rate constant (k) for the oxidation of D) of hydrazine was also estimated using chronoamperometry. The dynamic detection range of this sensor to hydrazine was 5- 60 and 80- quantitation are 5.33 μM and 17.77 μM, respectively. A new voltammetric method for determination of hydrazine was erected and shows good sensitivity and selectivity, wider linear relationship, very easy surface update and good stability.
