“…Unfortunately, hydrazine undergoes direct oxidation at the bare electrode surface, thus resulting in sluggish electrode kinetics and high over potentials [14,15]. Therefore, chemically modified electrodes have been used to detect hydrazine, which significantly reduce the overpotential, as well as accelerate redox reactions and hence the oxidation current responses [16,17].…”

Herein, we report the fabrication of a modified glassy carbon electrode (GCE) with high-performance hydrazine sensor based on Fe-doped TiO 2 nanoparticles prepared via a facile and low-cost hydrothermal method. The structural morphology, crystalline, crystallite size, vibrational and scattering properties were examined through different characterization techniques, including FESEM, XRD, FTIR, UV-Vis, Raman and photoluminescence spectroscopy. FESEM analysis revealed the high-density synthesis of Fe-doped TiO 2 nanoparticles with the average diameter of 25 ± 5 nm. The average crystallite size of the synthesized nanoparticles was found to be around 14 nm. As-fabricated hydrazine chemical sensors exhibited 1.44 µA µM −1 cm −2 and 0.236 µM sensitivity and limit of detection (LOD), respectively. Linear dynamic ranged from 0.2 to 30 µM concentrations. Furthermore, the Fe-doped TiO 2 modified GCE showed a negligible inference behavior towards ascorbic acid, uric acid, glucose, SO 4 2− , NO 3 − , Pb 2+ and Ca 2+ ions on the hydrazine sensing performance. Thus, Fe-doped TiO 2 modified GCE can be efficiently used as an economical, easy to fabricate and selective sensing of hydrazine and its derivatives.

“…Various instrument‐based methods to determine the concentration of hydrazines have been reported in the past. These mainly include spectrophotometric [2–4] and fluorescence techniques [5–11]. Out of these two techniques, spectrophotometric techniques are preferred as they provide reproducible results with good selectivity and high sensitivity.…”

Hydrazine and its derivatives such as monomethyl hydrazine (MMH), unsymmetrical dimethyl hydrazine (UDMH), and UH25 (a blend of 75 % UDMH and 25 % hydrazine hydrate by w/w) namely hydrazines are used as fuels (in liquid form) for rocket stages and satellites. They are hypergolic and well‐known toxic compounds. Workplace atmospheres involving vapours / liquid forms of these hydrazines need to be routinely monitored and screened. Simple, economical, and rapid kinetic spectrophotometric techniques are developed to meet the requirements by using thiophene‐3‐carboxaldehyde and 3‐butenone (E)‐1,1,1‐trifluoro‐4‐(3‐thienyl) (CF3enone) and compared. Classical −CHO based technique is applied for UH25 blend (in aqueous medium) in the presence of an acid catalyst. CF3enone based technique is used to determine hydrazine (Hz) in UH25 (in organic medium) selectively at levels as low as 0.05 mM without any catalyst. Variables such as temperature and concentration are optimized to determine UH25 in the concentration range of 0.5 mM to 0.1 M for thiophene‐3‐carboxaldehyde and to determine Hz of UH25 blend in the concentration range of 0.1 mM to 0.6 mM for CF3enone. Minimum detectable limits are found for UH25 and Hz of UH25 blend in the respective studies. GC‐MS study is also carried out to meet the unequivocal identification requirement. Initial rate and fixed time methods are adopted as calibration procedures. Orders of the reactions are found in both studies. Both techniques are simple and rapid after the chemisorption process with derivatizing agents in which pre‐treatment, pre‐concentration, and extraction steps are not involved. Advantages of CF3enone based technique over aldehyde‐based classical technique are 1) requirement of the minimum concentration of derivatizing agent 2) no catalyst 3) selectivity and specificity towards hydrazine in UH25 blend 4) shortened analysis time 5) linear dynamic range at very low concentrations of UH25.

“…[15][16][17] Compared with the analytical methods, fluorescent methods have benefits that include remarkable sensitivity, short response time, specificity, and a straightforward process. [18][19][20][21][22][23] In addition, fluorescent analysis could be applied in living organism. [24][25][26] Therefore, several fluorophores have been developed for recognizing hypochlorite, such as 1,8-naphthalimide, phenanthrene, rhodamine, BODIPY, fluorescein, coumarin, anthracene, and 1,8-diaminonaphthalene.…”

A novel fluorescent turn-off sensor JM for hypochlorite was synthesized. JM showed a remarkable selectivity for ClOover diverse competitive analytes, including reactive oxygen species (ROS), via deprotonation reaction. Detection limit for ClOturned out to be 0.60 μM. Sensor JM successfully determined ClOin natural water samples with satisfactory recovery. The sensing mechanism of JM to hypochlorite was demonstrated by fluorescent and UV-visible spectroscopy, ESI-mass, NMR titration and TD-DFT calculations.
