Amperometric determination of hydrazine using a surface modified nickel hexacyanoferrate graphite electrode fabricated following a new approach

Cobalt Hexacyanoferrate-Decorated Titania Nanotube: CoHCF@TNT Modified GCE as an Electron Transfer Mediator for the Determination of Hydrazine in Water Samples

“…From the cyclic voltammogram, it can be seen that the redox peak current for both Co 2+ /Co 3+ and Fe(CN) 6 4− /Fe(CN) 6 3− systems, and the separate redox peaks were merged together and showing a single redox peak. The increase in peak currents when increasing potential scan rates, confirming the redox behavior is due to the surface confinement of the redox species and also suggests that the redox reaction is purely diffusion-controlled one [30].…”

“…Therefore, chemically modified electrodes have been developed for the determination of hydrazine. Several types of modified electrode have been used for the electrocatalytic oxidation of hydrazine such as metal phthalocyanine [27,28], metal porphyrin [29], metal hexacyanoferrate [30,31], metal complexes [32], metal nanoparticles [33], and metal nanoparticles-modified MWCNT- [34] modified electrodes. Among these electron transfer mediators, metal hexacyanoferrates [35], metal hexacyanoferrate-modified metal oxide [36], and metal hexacyanoferrate-modified carbon nanotube [37] have been widely used for the electrocatalytic detection of hydrazine in various sources.…”

Cerium hexacyanoferrate/ordered mesoporous carbon electrode and its application in electrochemical determination of hydrous hydrazine

“…However, the hydrous hydrazine is a toxic material and has negative health effect, and it can cause the diseases such as headache, temporary blindness, DNA damage [15], and even on central nervous system. So the determination of hydrous hydrazine has drawn significant attention, and a reliable and sensitive detection method is highly expected.…”

Nanoporous gold particles modified titanium electrode for hydrazine oxidation

“…Palladium nanoparticles were applied to electro-oxidation of hydrazine as effective electrocatalysts including Pd particles on poly(vinylferrocenium) [13], Pd/WO 3 film [14], Pd nanoparticles decorated ionic liquid-modified carbon electrode [15], Pd/TiO 2 nanotubes [16], Pd nanoparticles on carbon nanotubes [17,18], and Pd nanoparticles supported on boron-doped diamond [19], etc. Nickel and modified nickel electrodes were also applied to amperometric determination of hydrazine [20,21]. In addition, electro-oxidation of hydrazine was performed at various modified glassy carbon and carbon nanotube electrodes [22][23][24][25][26][27][28], as well as silver or silver nanoparticles [29,30].…”
