The sensitivity enhancing properties of sodium dodecyl sulphate (SDS) and multi‐walled carbon nanotubes (MWCNTs) were associated to construct a nanosensor based on carbon paste electrode (CPE) by adopting drop cast method. The drop cast method makes use of minimum modifier and the entire modified surface of the sensor is available for the analyte. Surface characterization of the electrodes was carried out using FE‐SEM and EDX. EIS was used for the electrochemical characterization. We report for the first time the electrochemical analysis based on the oxidation of the ‐OH group of a novel drug, alpha‐hydrazinonitroalkene (I) which was found to have antibacterial and antimicrobial properties. The electron transfer kinetic parameters such as the charge transfer coefficient α and heterogeneous rate constant k′ were calculated and they have been found to be 0.64 and 9.62 × 10−2 cm s−1 respectively. The linear response ranges for (I) obtained at this sensor are 1.0 × 10−7 M − 7.0 × 10−7 M and 1.0 × 10−6 M – 4.5 × 10−5 M with a detection limit of (7.03 ± 0.41) × 10−8 M (S/N=3). The interference study suggested that the sensor was free from 1000‐fold excess of UA in the determination of (I). It was important to note that the sensor completely eliminated Ascorbic acid (AA) signal which offered a significant analytical advantage for the determination of the drug at this sensor. The practical usefulness of the modified sensor was demonstrated by the analysis of (I) in blood serum.

Manganese Molybdenum Oxide Micro Rods Adorned Porous Carbon Hybrid Electrocatalyst for Electrochemical Determination of Furazolidone in Environmental Fluids

et al. 2021

The frequent occurrence of furazolidone (FZD) in environmental fluids reveals the ongoing increase in use and raises concerns about the need of monitoring it. To investigate the electrochemical behavior of FZD, a novel sensor of manganese molybdenum oxide (MMO) micro rods adorned three-dimensional porous carbon (PC) electrocatalyst was constructed. The crystalline structure and surface morphology of the MMO/PC composite was characterized by XRD, Raman, FESEM, and HR-TEM. Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and amperometric(i-t) methods were used to assess the electrocatalytic activity of modified electrodes. In the presence of FZD, the as-fabricated MMO/PC modified glassy carbon electrode (GCE) performed better at lower potentials with a greater peak current than other modified GCE. These results emanate from the synergistic effect of the MMO/PC suspension on the GCE. The electrochemical behavior of the amperometric(i-t) technique was used to determine FZD. Amperometric(i-t) detection yielded linear dynamic ranges of 150 nM to 41.05 µM and 41.05 to 471.05 µM with detection limits of 30 nM. The MMO/PC hybrid sensor was also effectively used to detect FZD in environmental fluids, yielding ultra-trace level detection.
