“…Alternatively, electrochemical methods offer an attractive approach for hydrazine measurements due to their low cost, simple preparation, rapid response, high sensitivity, and potential as portable devices. − For these reasons, we selected electrochemical methods for hydrazine measurements for this present study. There are a plethora of electroanalytical methods that have been developed to provide electrochemical sensing of hydrazine based on the platform of the modified carbon electrode. − In addition, we have reported the utilization of the composite material of electrochemically reduced graphene oxide (ErGO) and conductive polymer-modified electrode for uric acid detection, but it remains interesting to explore our developed sensing platform for the detection of novel electroactive substance hydrazine. We expect that our developed sensing platform could be a versatile electrode for the detection of different electroactive substances.…”

In this study, hydrazine sensors were developed from a composite of electrochemically reduced graphene oxide (ErGO) and poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), deposited onto a glassy carbon electrode (GCE). The structural properties, electrochemical characterization, and surface morphologies of this hydrazine sensor were characterized by Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). In addition, the proposed hydrazine sensor also demonstrates good electrochemical and analytical performance when investigated using cyclic voltammetry (CV), differential pulse voltammetry (DPV), and amperometry techniques under optimal parameters. Using these investigated parameters, DPV and amperometry were chosen as techniques for hydrazine measurements and showed a linear range of concentration in the range of 0.2−100 μM. The obtained limits of detection and limits of quantitation for hydrazine measurements were 0.01 and 0.03 μM, respectively. In addition, the proposed sensor demonstrated good reproducibility and stability in hydrazine measurements in eight consecutive days. This fabricated hydrazine sensor also exhibited good selectivity against interference from Mg 2+ , K + , Zn 2+ , Fe 2+ , Na + , NO 2 − , CH 3 COO − , SO 4 2− , Cl − , ascorbic acid, chlorophenol, and triclosan and combined interferences, as well as it depicted %RSD values of less than 5%. In conclusion, this proposed sensor based on GCE modified with ErGO/PEDOT:PSS displays exceptional electrochemical performance for use in hydrazine measurements and have the potential to be employed in practical applications.
