Hydrazine has been identified as a carcinogenic mutagenic, hepatotoxic, and neurotoxin material. A metal-organic framework with tetragonal symmetry, DMOF-1 (Zn-2(bdc)(2)dabco) was synthesized by a versatile and facile technique, followed by its efficient development and validation as hydrazine electrochemical sensor. Differential pulse voltammetry (DPV), linear sweep voltammetry (LSV), and cyclic voltammetry (CV) techniques were used as diagnostic techniques. Scanning electron microscopy (SEM) and x-ray diffraction (XRD) were also used to characterize the MOF. In the electro-oxidation of hydrazine, there was a highly catalytic activity shown by the modified electrode. In addition, there was a greater signal response, compared to the unmodified electrode, which was primarily attributed to the large active surface area provided by DMOF-1. The detection limit for hydrazine, linear range, and sensor sensitivity were reported to be 0.02 mu M, 0.09-400.0 mu M, and 0.0863 mu A/mu M-1, respectively. Based on the results, the amplified sensor was able to properly analyze hydrazine in different samples of water.
