“…Many techniques such as spectrophotometry, chromatography and electrochemical methods have been reported in the literature to detect nitrite ion, but the former two techniques are complicated and time-consuming. The electrochemical methods have advantages over the other methods as the tests are faster, cheaper and more secure in general [5,6]. The electrostatically self-assembled (ESAM) film-modified indium-tin oxide (ITO) electrodes are particularly attractive on this respect [7].…”

“…Moreover, the development of a rapid electrochemical method for nitrite detection without the sample pretreatment prior to analysis and also no interface from other sources (for instance nitrate, sulfate, bromate ions, and oxygen) is highly important. Recently, various kinds of electrochemical nitrite sensors have been fabricated based on the chemical modification of electrode [12][13][14][15][16][17][18][19][20][21][22][23]. In addition, the electrochemical nitrite sensors usually work under weak acidic medium to obtain high sensitivity.…”

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.

Copper-cobalt bimetal nanoparticles (Cu-Co) have been electrochemically prepared on glassy carbon electrodes (GCEs), which were electrodeposited with conducting polymer nanocomposites of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with carbon nanotubes (CNTs). Owing to their good conductivity, high mechanical strength, and large surface area, the PEDOT/CNTs composites offered excellent substrates for the electrochemical deposition of Cu-Co nanoparticles. As a result of their nanostructure and the synergic effect between Cu and Co, the Cu-Co/PEDOT/CNTs composites exhibited significantly enhanced catalytic activity towards the electrochemical oxidation of nitrite. Under optimized conditions, the nanocomposite-modified electrodes had a fast response time within 2 s and a linear range from 0.5 to 430 μm for the detection of nitrite, with a detection limit of 60 nm. Moreover, the Cu-Co/PEDOT/CNTs composites were highly stable, and the prepared nitrite sensors could retain more than 96 % of their initial response after 30 days.
