“…In fact, it is conrmed by the absence of the cathodic peak in the voltammetric curves (see Fig. 1c) and by electrooxidation mechanisms that are already well-known in the literature 41,42 where the formation of polymer layer is achieved, which deactivates the catalytic sites of the anode. 43 These effects of isomers have been described in the literature 14,15,17,33,35,37 and these have been claimed to explain the electrochemical behaviors obtained in numerous of oxidation processes; for this reason, mechanistic studies must be performed to increase the understanding on the oxidation pathways and on the viability of detection of these isomers.…”

“…In fact, this behavior is in accordance with the voltammetric results because in all cases, the oxidation of the isomers to their quinones is attained. 1,32,42 On the other hand, signicant differences are observed between the EA values for HQ, CT and RS (see Table 1). The energy released by HQ and CT is higher and these values are very similar in both cases, indicating that, the product formed is very stable (in vacuum or implicit solvent).…”

“…To prevent blockage, the electrode surface was refreshed after each scan, as described in Section 2.3. Similar deactivation of different working electrodes in the presence of phenolic compounds has already been reported . Based on these findings the peak current of the first potential scan was considered for further analysis.…”

Electroanalysis of the Anthelmintic Drug Bithionol at Edge Plane Pyrolytic Graphite Electrode

et al. 2019

An electrochemical study of the anthelmintic drug bithionol using edge plane pyrolytic graphite electrode (EPPGE) is presented for the first time by applying different electrochemical techniques, such as cyclic voltammetry (CV), square‐wave voltammetry (SWV), square‐wave adsorptive stripping voltammetry (SWAdSV), and alternating current (AC) impedance spectroscopy. Mechanistic aspects of the electrode reaction were studied implying a quasireversible electrode reaction from an adsorbed state of the reactant, coupled with a follow‐up chemical reaction to a final electroinactive product. The overall mechanism appears totally irreversible under conditions of CV at moderate scan rate, while being quasireversible under conditions of the fast SWV. Furthermore, an optimisation of the analytical procedure for quantitative determination of bithionol was conducted by applying SWV in an adsorptive stripping mode. The calibration curve was constructed in the concentration range of 0.1–1.0 μmol L−1 (R2=0.9984) with a sensitivity of 3.6 μA L μmol−1 and LOD of 26.7 nmol L−1. The simple and sensitive SWAdSV procedure was proved to be suitable for the analysis of spiked urine samples.

“…High-end industries use high-quality materials such as phenolic compounds which are materials with phenolic content that are hazardous pollutants with low degradability [1]. Therefore, there is a huge need to substitute materials made from phenolic compounds with biodegradable, nontoxic materials to fulfill environmental and sustainability issues.…”

In this paper, hybrid composites were fabricated by using kenaf and recycled carbon with a cashew nut shell liquid (CNSL) derivative known as cardanol as the matrix by a compression molding technique. In this work, we look for the effect of recycled carbon weight loading (15%, 25%, and 35%) on the thermal properties of kenaf/cardanol composites while maintaining the total fiber loading of 50 wt%. TGA, DSC, DMA, and flammability UL 90 HB properties of the specimens were studied. The results indicate that cardanol improved the thermal stability of kenaf and hybridization with recycled carbon also further improved the thermal stability of the specimens. The flammability UL 90 HB test determines the flame retardancy property of all specimens.
