“…[1][2] The ability of the conductive/electroactive polymers such as polypyrrole, poly(1-naphthylamine), poly(ortho-toluidine) etc., for the fabrication of the modified electrodes prepared by an electropolymerization procedure have been demonstrated. [3][4][5][6][7] On the other hand, nitrite ion (NO 2 -) has been reported as a human health -hazard which extensively exists in the environment and usually uses in food preservation against food poisoning microorganism such as clostridium botulinum.…”

In this study, the electrochemical reduction of nitrite was investigated on poly(4-aminoacetanilide) (PPAA) forming by cyclic voltammetry at the surface of carbon paste electrode. The electrochemical properties of the modified electrode have been studied by cyclic voltammetry and double potential step chronoamperometry. Results showed that in the optimum condition (pH = 0.00) the reduction of nitrite occurred at a potential about 667 mV more positive than that unmodified carbon paste electrode. This amount of electrocatalytic ability is high compared with other electrocatalysts. Using a chronoamperometric method, the catalytic rate constant (k) was calculated 8.4 × 10 4 cm 3 mol -1 s -1 . Also, the electrocatalytic reduction peak currents was found to be linear with the nitrite concentration in the ranges of 5 × 10 -4 M to 2.5 × 10 -2 M and 2 × 10 -5 M to 7 × 10 -3 M with detection limits (2s) were determined as 4.5 × 10 -4 M and 1 × 10 -5 M by cyclic voltammetry (CV) and hydrodynamic amperometry methods respectively. Recovery experiments exhibit the satisfactory results.

“…6,7 Various PMEs were studied towards the electrocatalytic oxidation of DA, UA and AA. [8][9][10][11][12] For example, a glassy carbon electrode (GCE) modified with poly(N,N-dimethylaniline) could simultaneously detect AA and DA which coexisted in a homogeneous solution. 9 There have been concerned the use of glutamic acid, 10 aminobenzoic acid 11 and p-nitrobenzenazo resorcinol 12 as an electropolymerized layer to modify GCE for the detection of DA.…”

“…By using different electropolymerizing conditions, including monomer concentration, solvent conductivity, pH value, scanning-potential range, and applied scanning cycle, dif-ferent characteristics and functions of the conducting films can be obtained [2][3][4][5][6][7][8][9]. Differences in electropolymerized polymer film include thickness, surface roughness, pH response [4,5], electron-transfer kinetics [3,7], protection against metal corrosion [6], permselectivity for a dissolved species [2], and electrochromic properties [8]. Furthermore, the sensing efficiency of the sensor is related to the thickness of the electropolymerized polymer film.…”

A novel method to measure ultrathin poly(o-phenylenediamine) (PPD) film electropolymerized on gold electrode in liquid was developed.It is based on the force versus distance curve (force curve) of atomic force microscopy (AFM). When 1-0.25 m/s was chosen as the rising rate of the scanner, and 50% of the confidence interval (CI) as the qualifying threshold value, the thickness of the hydrated polymer film could be calculated. This result was compared with one obtained from an AFM image. A step-like electrode fabricated by a photolithographic process was used. The height difference of the electrode before and after the PPD coating was imaged in liquid, and then the real thickness, 19.6 ± 5.2 nm, was obtained. The sample was also measured by estimating the transition range of the force curve of hydrated PPD film, and the thickness of the hydrated PPD film was determined to be 19.3 ± 8.2 nm. However, the results calculated by integrating the electropolymerized charge for the oxidation process of o-phenylenediamine (o-PD) was only one-third as large as it was when using the two previously described methods. This indicated that the structure of hydrated PPD film might have been swollen.
