“…Nitrite is an intermediate species of the nitrogen cycle. [1] It is often used as food preservative in order to resist the growth of harmful bacteria [2][3][4][5] and investigated for corrosion inhibition. [6] The higher use of nitrite can lead to certain detrimental effect on living beings.…”

The present work describes the electrocatalytic oxidation of nitrite in the presence of a composite of coordination polymer of cobalt‐4‐pyridylporphyrin and electrochemically reduced graphene oxide. The electrode was modified by drop‐casting a suspension of graphene oxide and polymeric cobalt‐4‐pyridylporphyrin followed by reduction through cyclic voltammetry in the potential range 0.0 V to −1.5 V. The electrocatalytic investigations were carried out by voltammetric (cyclic, linear sweep, differential pulse and hydrodynamic) and by amperometric methods. The LOD and the working range obtained through different techniques are compared. The rate constant for this heterogeneous electron transfer reaction is 2.45×10−2 cms−1.

“…50,51 MWCNTs can be used as an effective substrate to enhance the sensitivity due to their excellent properties including large specic surface area, and unique porous and hollow structure. [52][53][54][55][56] On the basis of a MWCNT modied glassy carbon electrode, a molecularly imprinted sensor using L-glutamic acid (L-Glu) as a template and 4,6-diaminoresorcinol as a functional monomer was fabricated through electrochemical polymerization in the present work. Compared to the previous achievements for L-Glu determination, the electrochemical polymerization technique used in this study simplied the material fabrication with increased binding sites toward templates by the functional monomers and improved sensitivity by using MWCNTs.…”

“…Although the detection of nitrite via electroreduction has emerged as a promising [4,7,9,[13][14][15][16][17][18][19][20][21][22][23], its low sensitivity and the presence of interferences have limited its practical application. The use of traditional bare electrodes for nitrite electrodetection, such as platinum, gold, and glassy carbon, is thermodynamically advantageous; however, the charge transfer kinetics associated with the reaction is slow.…”

In this article, poly(1,2-diaminoanthraquinone) (pDAAQ) and poly(1,5-diaminonaphthalene) (pDAN) were electrochemically deposited layer by layer on a glassy carbon electrode (GCE) to generate pDAAQ/ pDAN@GCE and pDAN/pDAAQ@GCE composite electrodes, respectively. The morphology and characteristics of the modified electrodes were investigated via electrochemical impedance spectroscopy)EIS), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy)SEM). The obtained results reveal the outstanding performance of the pDAN/ pDAAQ@GCE electrode for electrochemical nitrite sensing where pDAAQ plays a vital role as the inner layer. Cyclic voltammetry (CV), linear sweep voltammetry (LSV), and differential pulse voltammetry (DPV) measurements revealed that the oxidation peak current of nitrite was proportional to its concentration. The best LSV results were obtained in a concentration range of 10-150 μM, with a limit of detection of 1.2 μM. Furthermore, the pDAN/pDAAQ@GCE composite electrode was used to determine nitrite ions in real water samples with good results.
