“…Consequently, a poorly defined film, with continuous structure is formed on the electrode surface. An analogous reaction path was previously proposed for oxidative polymerization of vanillin porphyrins [13], vanillin [14], guaiacol [15], epidotoxin [16] and eugenol [17].…”

The voltammetric behavior in alkaline solution of a nickel-based chemically modified electrode (poly-Ni(II)curcumin) prepared by oxidative electropolymerization of nickel-curcumin complex for electrooxidation of aliphatic alcohols was investigated by cyclic voltammetry and rotating disk technique (curcumin 1,7-bis[4-hydroxy-3-methoxyphenyl]-1,6-heptadiene-3,5-dione). The dependence of the oxidation current on the alcohol concentration and on the number of redox centers Ni(II)/Ni(III) is discussed. From the fact that the oxidation current increases with the increase of film thickness it is evident that the electrocatalytic reaction occurs inside the polymer film. The system examined is a typical example of a redox polymer with 3D properties. It is also concluded that the reaction mechanism of alcohol oxidation is the case, according to the concept of Andrieux and Saveant, where the cross-exchange reaction is the limiting step. The mechanism of modifying the film formation has also been discussed.

“…The increase of ∆I in the NO2 -detection for 3 wt% Nafion ® /2-propanol is thought to be due to inhomogeneous coating by the Nafion ® film on the electrode surface with uncovered region due to formation of aggregates of Nafion ® . [28][29][30] and NO concentration ranges 1.3 -4.1 and 0.5 -10 μM, respectively, indicating successful detection of these species at the Nafion ® /FePor-modified electrode (Fig. 8).…”

“…The third distillation was carried out using an all-quartz still. Nickel(II) tetrakis(3-methoxy-4-hydroxyphenyl)-porphyrin (NiTMHPP) was synthesized according to a procedure described previously [12]. Standard saturated NO solutions were prepared by bubbling argon through phosphate buffer solution (pH 7.4) for 30 min to remove oxygen and then the solution was bubbled with pure NO gas (Aldrich) for 30 min and kept under NO atmosphere until use.…”

Oxidation of Nitric Oxide at a Porphyrinic-Based SensorNew Results from Rotating Disk Experiments

et al. 1998

View full text Add to dashboard Cite

An amperometric sensor for the determination of nitric oxide based on its oxidation on a glassy carbon electrode modified with electropolymerized vanillin porphyrin [tetrakis(3-methoxy-4-hydroxyphenyl)porphyrin] film and Nafion is described. Our results show that the anodic oxidation of NO at the modified electrode is the result of a catalytic effect induced by the porphyrinic modifier, that acts as a 3D system. The effect of film thickness of both porphyrinic modifier and Nafion on the NO response is tested. The results of rotating disk electrode experiments are presented and a general mathematical model of the working sensor is also given.
