Abstract EN
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 CoCl2 · 6H2O and K3[Fe(CN)6] containing 0.05 M KCl solution (35 mL).
The TNT was synthesized by hydrothermal method using Degussa P-25 TiO2 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.
