Due to the importance of the amount of hydrazine in water samples from the environmental point of view as well as frequent usage of this matter, the concentrations of this substance were to be measured in different samples. In this study, a new and simple electrode was fabricated for measuring hydrazine. The electrode was a carbon paste electrode modified by strontium ferrite nanoparticles. The electrode showed good sensitivity and selectivity for the electroanalysis of hydrazine due to the presence of nanoparticles. Voltammetric and chronoamperometric techniques proposed a good catalytic oxidation of hydrazine at the electrode surface. The hydrazine sensor was showed two linear calibration range which covers 0.5 to 20 micromolar and 20 to 600 micromolar. The selectivity of the electrode for measuring the hydrazine was good. Also the repeatability, reproducibility, and lifetime of the electrodes were acceptable. Determination of hydrazine in aqueous samples such as tap water and well water were performed. The obtained recovery percentages showed that the ability of the electrode in determination of real samples is reliable
