A graphite electrode modified with cobalt hexacyanoferrate by mechanical immobilization was used for amperometric determination of hydrazine. The modified electrode exhibits good catalytic activity for the oxidation of hydrazine at a reduced overpotential with remarkable sensitivity. The modified electrode showed a linear response for hydrazine in the concentration range of 2.0 × 10–5 to 2.8 × 10–4 M. The detection limit was 9.8 × 10–6 M (S/N = 3). The proposed modified electrode was simple, sensitive, rapid, stable and promising.

A nickel hexacyanoferrate modified electrode was constructed by mechanical immobilization. A reversible peak with midpoint potential of 0.38 V was observed in cyclic voltammetry with 0.1 M NaNO3. Electrocatalytic oxidation of thiosulfate was effective on the modified electrode at a significantly reduced overpotential of 0.5 V and at broad pH range. The modified electrode can be used for the determination of thiosulfate in the concentration range of 7.0 × 10–4 to 5.6 × 10–3 M. It has been used fo...

A newly modified electrode was prepared by mechanical immobilization of copper hexacyanoferrate (CuHCF) on a graphite electrode. The modified electrode was characterized by cyclic voltammetric experiments. The effect of different background electrolytes, pHs and scan rates on the electrochemical behaviour of the electrode has been evaluated. In NH4Cl two reversible redox peaks were observed. The first redox peak corresponding to Cu+/Cu2+ is observed only in this medium. The second redox peak cor...

Abstract Copper hexacyanoferrate (CuHCF) modified graphite electrode prepared by mechanical immobilisation method has been used for the amperometric determination of sulphite, which can be extended for the determination of SO 2 in air after absorbing the pollutant in sodium hydroxide solution. This method is based upon the electrocatalytic oxidation of sulphite by the modified electrode. The pH of the medium for oxidation should be in the range of 3.5–8.0. The range of determination of SO 2 is f...

Oxidized and reduced cobalt(II) hexacyanoferrates were fabricated and characterized in the presence of alkali metal (Li+, Na+, K+, Cs+) and Co2+ countercations. Formal potentials of hexacyanoferrate(III,II) redox reactions are sensitive to the choice of electrolyte cation, and they correlate well with the sizes of hydrated Li+, Na+, and K+. Electrochemical quartz crystal microbalance measurements clearly indicate that countercations, presumably in partially dehydrated form, are incorporated into...

Abstract A sensitive and selective flow injection chemiluminescence method for the determination of hydrazine over the range 1×10 −6 −5×10 −5 M is described. The method is based on the chemiluminescence emitted during the oxidation of hydrazine by N -bromosuccinimide in alkaline medium in the presence of dichlorofluorescein as sensitizer. The presence of citrate prevents the precipitation of some cations in the reaction medium and also causes an enhancement in chemiluminescence intensity. Method...

Cobalt(II) hexacyanoferrate(III, II) films show reversible electrochromic behavior in potassium salt electrolyte. Gold-covered foil was used as a conductive, optically transparent substrate onto which cobalt hexacyanoferrate films were deposited by a slow coagulation method. Both voltammetric and spectroelectrochemical results are consistent with the existence of two cobalt hexacyanoferrate forms, presumably KCoII1.5[FeII(CN)6] and K2CoII[FeII(CN)6]. The separate nature of the redox reactions of...

Cobalt(II)-cyanoferrate polymeric film has been electrochemically deposited on a glassy carbon electrode and investigated by cyclic voltammetry and in-situ reflection FTIR spectroscopy. A reorientation of the terminal C=N groups upon redox reactions was proposed. The stretching vibration mode of the terminal C=N groups associated with Fe(III) was observed at 2122 cm(-1), however, the stretching vibration mode for terminal groups associated with Fe(II) did not appear. This process could result in...

A remote electrochemical sensor for field monitoring of hydrazine compounds is described. The new submersible probe relies on the coupling of an effective electrocatalytic modified electrode to a 50 ft long shielded cable. The catalytic surface, based on an electorpolymerized film of 3.4-dihydroxybenzaldehyde, offers low-potential detection of hydrazine compounds. Such catalytic activity results in high sensitivity and selectivity, and hence offers convenient measurements of micromolar hydrazine...

The electrocatalytic oxidation of hydrazine has been studied on glassy carbon electrodes modified by electrodeposition of iron(III)hexacyanoferrat(II) (Prussian Blue PB), by using cyclic voltammetry and the rotating disc technique. The oxidation of hydrazine to nitrogen occurs at the rising part of the oxidation wave of PB to Berlin Green at 0.7V vs. AgAgCl where oxidation is not observed at the bare glassy carbon electrode. The dependence of the oxidation current on the hydrazine concentration ...

In this paper, for the first time, we introduce a simple and low cost hydrazine sensor based on a commercial junction field-effect transistor (JFET). The transistor was mechanically treated, isolated, and used as an ion sensitive FET (ISFET) for hydrazine detection, after the electrodeposition of the sensing membrane on its metal gate surface. Copper hexacyanoferrate nanoparticles as suitable sensing membrane were electrodeposited on the copper metal gate of transistor from a solution containing...

Abstract A novel low-cost and highly efficient hydrazine sensor based on nitrogen-doped carbon nanopolyhedra (CNP), Prussian blue (PB) and conductive polymer is synthesized. CNP containing cobalt, which were prepared via pyrolysis of the Zeolitic Imidazole Framework-67 (ZIF-67), are found to be catalytically active for the synthesis of PB. Polypyrrole (PPy) is then coated on the PB/CNP composite to provide high conductivity and an environmental stability of the PB/CNP/PPy compound. The as-prepar...

Abstract In this paper, for the first time, we introduced the seed-mediated method to the growth of cobalt hexacyanoferrate nanoparticles (CoNPs), using 3.5 nm gold nanoparticles as seeds and multiwalled carbon nanotubes (MWCNTs) as growth scaffold which would both show synergistic action toward the reduction of H 2 O 2 . Via gold seeds, the one-step fabrication of CoNPs on the glassy carbon electrode is simple without any linking reagents, which will ingeniously exert the electrochemical proper...
