Abstract: A low cost and commercial available screen printed electrode, copper oxide nanoparticles/carbon nanotube (CNT) modified screen printed electrode for electrocatalytic oxidation of hydrazine. For preparation of electrode copper oxide nanoparticles prepared by coprecipitation method and mixed manually with CNT dispersed in phosphate buffer solution (PBS). Cyclic voltammetry experiments shows oxidation of hydrazine was observed at 804 mV with an Ipa value of 970 A. The recorded amperometric current-time curves showed a linear dependence on the hydrazine concentration 5 M to 50 M with a detection limit of 5 M in response time< 5 s. This proposed modified exhibits a rapid, low cost and sensitive determination of hydrazine.

 

Keywords: Copper oxide nanoparticles, Co-precipitation method, XRD, SEM, Optical properties.
