Zinc Oxide Modified Au Electrode as Sensor for an Efficient Detection of Hydrazine
Wajeeha Sultana, Somnath Ghosh, B. Eraiah / Somnath Ghosh
Аннотация ZnO nanoparticles (ZnO NPs) prepared by microwave heating technique are used to modify a gold electrode (ZnO/Au) for the hydrazine detection study. The synthesized product is well characterized by various techniques. Detailed electrochemical investigation of the oxidation of hydrazine on the ZnO/Au electrode in 0.02 M phosphate buffer solution (PBS) of pH 7.4 was carried out. A very low detection limit of 66 nM (S/N=4) and a wide linearity in current for a concentration range from 66.0103 to 415 mM was achieved by amperometry. The electrode was found to be stable for over a month when preserved in PBS.
