“…The values of D are calculated to be 1.89 × 10 −5 cm 2 /s and 2.89 × 10 −6 cm 2 /s for PANI and POT, respectively indicating that polyaniline is a superior sensing material for hydrazine, which is understandable owing to the steric hinderance offered by methyl group in POT. The value of D obtained from the polymer‐based sensors developed in this work is superior to the values reported for hydrazine detection using nanostructured sensing materials, as reported in literature 43,44 …”

This work presents a comparative experimental and theoretical study on the use of polyaniline and its derivative, poly o‐toluidine, as effective electrochemical sensor for the detection of hydrazine. Hydrazine is a toxic analytic with numerous adverse health effects on the human brain, liver and nervous system. The conducting polymers polyaniline (PANI) and poly o‐toluidine (POT) were synthesized by oxidative polymerization and characterized through x‐ray Diffraction, FT‐IR, and UV–Visible Spectroscopy. Electrochemical studies performed on the polymer modified glassy carbon electrode (GCE) using cyclic voltammetry and differential pulse voltammetry reveal strong interaction between hydrazine and the polymer through irreversible charge transfer. The oxidation current was seen to increase with increasing hydrazine concentration. The diffusion coefficients were found to be 1.89 × 10−5 cm2/s and 2.89 × 10−6 cm2/s for PANI and POT, respectively. PANI and POT based sensors show a limit of detection of 1 μM and 5.13 mM, respectively in the linear concentration range of 1–9 mM. Density functional studies on the PANI‐hydrazine and POT‐hydrazine complexes show enhanced intermolecular charge transfer from nitrogen lone pairs in hydrazine to the polymer backbone clearly identifying the donor and acceptor moieties. PANI based electrochemical sensor is shown to have a higher sensitivity for hydrazine compared to POT, where the sensing interaction is hindered by the bulky methyl group in ortho position.

“…However, these methods employ various reagents, require specific skills to operate sophisticated instruments, and are time consuming and thus not practical for in situ analysis. 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.…”

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.
