“…11,12 Therefore, development a credible and sensitive sensor to detect nitrite in food, drinking water and environmental samples has received continued attention over the past 10 years. Several methods have been developed for nitrite determination, including spectrophotometry, 13,14 chemiluminescence, 15 chromatography, 16,17 capillary electrophoresis 18 and electrochemical methods. [19][20][21][22][23][24][25] Many of these procedures are time-consuming, but the electrochemical technique can provide cheaper, faster and real-time analysis.…”

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.

“…Therefore, it is of great importance to accurately monitor nitrite for public health, environmental, and food industries. Many methods have been developed for nitrite determination including spectrophotometry [8], chemiluminescence [9], capillary electrophoresis [10], chromatography [11], and electrochemical methods. Among these, electrochemical methods are advantageous over the other methods due to low cost while efficiency.…”

A new kind of nitrite sensor based on 3C-SiC whisker electrode was fabricated to electrochemically determine nitrite. Powder X-ray diffraction, field emission scanning electron microscope, and transmission electron microscopy reveal SiC whiskers are cubic single crystalline with some microtwins. The prepared SiC whisker electrode is examined for the electrochemical detection of nitrite under neutral condition using cyclic voltammetry and differential pulse voltammetry techniques. The results demonstrate that SiC whisker electrode fast responses toward nitrite with a detection limit of 3.5 × 10 −6 mol L −1 , which is comparable to the values reported in the recent literatures. The synthesized electrode is also successfully applied to determine nitrite in tap water.

A polyaniline (PANI)-Cu nanocomposite-modified electrode was fabricated by the electrochemical polymerization of aniline and the electrodeposition of copper under constant potentials on a glassy carbon electrode (GCE), respectively. Scanning electron microscope result shows that the PANI-Cu composite on the surface of the GCE displays the nanofibers having an average diameter of about 80 nm with lengths varying from 1.1 to 1.2 lm. The electrode exhibits enhanced electrocatalytic behavior to the reduction of nitrite compared to the PANI-modified GCE. The effects of applied potential, pH value of the detection solution, electropolymerization charge, temperature, and nitrite concentration on the current response of the composite-modified GCE were investigated and discussed. Under optimal conditions, the PANI-Cu composite-modified GCE can be used to determine nitrite concentration in a wide linear range (n ¼ 18) of 0.049 and 70.0 lM and a limit of detection of 0.025 lM. The sensitivity of the electrode was 0.312 lA lM À1 cm À2 . The PANI-Cu composite-modified GCE had the good storage stability.
