“…Carbon nanotubes are utilized not only as ion-selective electrodes for metal ion analysis but also for non-metal analysis, particularly organic compounds. Evtyugin and Porfir'eva [12] developed a method for the voltammetric detection of phenols and their derivatives using carbon nanotubes. Additionally, Madrakian et al [13] successfully determined tyrosine, acetaminophen, and ascorbic acid compounds through voltammetry with carbon nanotube electrodes.…”

This work developed a selectively modified electrode for measuring the Fe(II) ions in continuous integration using voltammetry techniques. The study assessed various aspects, such as linearity, scan rate, repeatability, and real sample analysis. The experiment is performed using differential pulse voltammetry (DPV). The findings of the study indicated that the voltammetry method exhibited a regression line of y = 36.507 ln(x) + 990.73, with a correlation value of 0.9627, with an optimum scan rate of 20 mV/s and good repeatability over five times measurement. On the other hand, when comparing the results using the UV-Vis spectrophotometric technique, the regression equation was found to be y = 0.20438x − 0.06987, with a correlation value of 0.99583. Notably, the voltammetry measurement outperformed the UV-Vis method since it allowed analysis of Fe(II) at concentrations up to 6.35 × 10−4 ppm (or 1.00 × 10−11 M), while the UV-vis measurement could only analyze up to 1.5 ppm (or 2.36 × 10−5 M). Consequently, the developed technique proves to be superior to the other methods for the analysis of Fe(II).

The heterocyclic and aromatic nitro compounds are industrially and commercially important chemicals, used in drugs, explosives, pesticides, and dyes. Despite their economic importance, the advent of these chemicals also brought serious human health and environmental problems due to their toxic characteristics as contaminants and pollutants. The nitro group is catalyzed in vivo by nitroreductases promoting a six-electron reduction to form sequentially the nitro radical anion, nitroso-, N-hydroxylamino and amino-functional groups. These reactions can be electrochemically reproduced, involving the development of analytical methods and electrochemical sensors, degradation and removal of organic compounds in effluents, corrosion studies, and studies of action mechanism of drugs on DNA bases. In this sense, a bibliometric analysis has been performed based on the Web of Science Core Collection in conjunction with VOSviewer software for generating network visualizations. This research covered the database until 2023, describing the main research areas and the annual publication trends, the collaborations and contributions among countries and research institutions, in addition to identifying the most cited articles, hotspots, and the analysis of evolution and relevance of keywords. This investigation made it possible to recognize the main research focuses and what is under development, providing a comprehensive overview on electrochemistry of nitro compounds.
