Electroanalysis of nirofurazone at silver particles and graphite powder composite electrode

Abstract

The main objective of the research was to deposit thin films of silver on a graphite carbon paste in a phosphate buffer medium using an electrochemical method. To construct a nitrofurazone detection sensor that is highly sensitive. Different manufacturing parameters, such as electrodeposition potential, pH effect, potential scan rate effect, and number of scan cycles, were examined in this section. The parameters were optimized to improve the deposited silver layers various electrocatalytic characteristics. The Nitrofurazone reduction process is diffusion controlled, as seen by the linear variation of Epc with log(v). The constructed Ag-NPs@CPE electrod has excellent electrical characteristics a large active surface area and low background with extremely high electrical conductivity, according to structural and electrochemical characterizations such as Scanning electron microscopy, X-ray diffraction (XRD) and cyclic voltammetry. The constructed sensor has a very remarkable analytical performance for nitrofurazone molecule identification, with a very low detection limit of about 10 -8 M. The detection of nitrofurazone using our Ag-NPs@CPE sensors in real samples contaminated with the antibiotic nitrofurazone, such as tap water and urine. In the selected sample, the electroanalytical findings reveal a very satisfactory recovery rate of more than 94 percent.

Electrochemical sensor based on a ZnO-doped graphitized carbon for the electrocatalytic detection of the antibiotic hydroxychloroquine. Application: tap water and human urine

“…We calculated the total number of electrons participating in the oxidation of the hydroxychloroquine molecules electron donor group using the following formula for irreversible reactions [ 5 , 49 – 53 ]: αn = 0.048/Ep–Ep 1/2 . Where n is the number of oxidizing electrons, is α the charge transfer coefficient, and Ep 1/2 is the potential at half the maximum current.…”

Voltammetric study in aqueous media of two new sulfonylhydrazone derivatives as candidates for antichagasic drugs

“…As already mentioned above, the detailed understanding on the voltammetric reduction of nitroheterocyclic compounds is consolidate [7,20,21]. As the NTBS and NFBS designing was based on nitrofurazone as a prototype, its voltammetric behavior in aqueous media was taken as reference for present study, considering the drug determination in different matrixes by using modi ed electrodes [33][34][35], boron-doped diamond electrode [36], carbon ber electrode [37], as well as the voltammetric study of nitro-anion radical kinetic stability by applying different working electrodes such as mercury [38], glassy carbon [22,23], boron-doped diamond [39], DNA biosensor [40], carbon ber [24] and carbon nanotubes [41]. Thus, from Fig.…”

Gadolinium molybdate decorated graphitic carbon nitride composite: highly visualized detection of nitrofurazone in water samples

“…Hence, the GCE/g-C 3 N 4 /Gd 2 MoO 6 electrode has the potential for the selective and sensitive detection of NFZ. Moreover, the detection limit of the NFZ at the GCE/g-C 3 N 4 /Gd 2 MoO 6 electrode is lower than that of the other modified electrodes such us, Ag + @UiO-66-NH 2 /CsPbBr 3 /GCE-ECL electrode (LOD = 0.09 μM), 1 Ag-SDS fabricated electrode (LOD = 0.37 μM), 5 poly ACBK/GCE electrode (LOD = 0.250 μM), 9 [Ru–PMo/PDDAg–GO] 3 electrodes (LOD 50.0 μM), 4 LMNSs/SPCE electrode (LOD = 0.08 μM), 47 Ag 2 S QDs/g-C 3 N 4 electrode (LOD = 0.054 μM), 48 hollow MIL-101/GCE electrode (LOD = 0.01 μM), 2 Ag-NPS@CPE electrode (LOD = 0.012 μM), 3 WS 2 QDs electrode (LOD = 0.055 μM) 49 and PACBK/GCE electrode (LOD = 0.028 μM) 50 exhibit the NFZ detection at long linear response range than other aforementioned modified electrode due to the large surface area as well as the higher electrocatalytic effect.…”
