“…2 Therefore, quick and highly sensitive methods for the determination of hydrazine are required for environmental and biological analysis. 3 Numerous methods have been developed for the determination of hydrazine, such as chromatography, 4 spectrometry, 5,6 chemiluminescence, 7 flow injection analysis, 7,8 and electrochemical techniques. [9][10][11][12] Among them, in light of their fast response, high sensitivity, low cost, etc., 13 the electrochemical techniques are considered to be relatively direct and effective for the detection of hydrazine.…”

“…Its poisoning induces vomiting, severe irritation of the respiratory track, and long-term exposure affects the central nervous system. Hydrazine can be determined by several instrumental methods including chromatography [23], spectrophotometry [24], capillary electrophoresis [25] and fluorimetry [26]. Among these techniques, the electrochemical method is found to be a simple and an easy way to estimate hydrazine.…”

The cobalt hexacyanoferrate-decorated titania nanotube (CoHCF@TNT) was prepared by dispersing 100 mg of titania nanotube (TNT) to a solution of an equimolar concentration of CoCl 2 · 6H 2 O and K 3 [Fe(CN) 6 ] containing 0.05 M KCl solution (35 mL). The TNT was synthesized by hydrothermal method using Degussa P-25 TiO 2 in 2 M NaOH as reported in the literature. The CoHCF@TNT was isolated and characterized by DRS-UV, FE-SEM, FT-IR, and XRD analysis. The electrochemical behavior of the CoHCF@TNT was carried out in 0.1 M phosphate buffer. The CoHCF@TNT modified system showed an excellent electron transfer mediator for the oxidation of hydrazine at +0.5 V versus Ag wire. The proposed method can be utilized for the amperometry detection of hydrazine from environmental samples. A calibration plot was constructed by plotting the concentration of hydrazine against the peak current. The current response was linear in the ranges of the hydrazine concentration from 5 × 10 −4 M to 2.5 × 10 −3 M with a slope of 72.8 μAmM −1 and the linear correlation coefficient of 0.9972. The detection limit was found to be 1 × 10 −3 M.
