“…The calculated apparent diffusion coefficient is in a good agreement with some of those previously reported forhydroxylamine, 32,41,42 but is lower than the values which are reported in some other published papers. 14,40,43 Amperometric studies of electrocatalytic oxidation of hydroxylamine at the OBMWCNT-GCE surface…”

“…Also, a combination of MWCNT and a mediator (OB here) definitely improves the characteristics of hydroxylamine oxidation. Also, the peak potential of hydroxylamine oxidation at the OBMWCNT-GCE is less positive, in most cases, in comparison with those reported for electrodes modified with other mediators such as rutin, 14 nickel hexacyanoferrate, 16 a coumestan derivative, 32 gold nanoparticle-polypyrrole nanowire, 40 an indenedione derivative, 41 chlorogenic acid, 42 4-hydroxy-2-(triphenylphosphonio)phenolate, 43 and ruthenium oxide nanoparticles. 44 The oxidation potentials of hydroxylamine on different modified electrodes are shown in Table 2.…”

“…Figure 4A Table 2, the analytical parameters of electrocatalytic determination of hydroxylamine in this work are compared with the corresponding values previously reported for some other modified electrodes. 10,14,16,32,[40][41][42][43][44] It can be seen that the responses made by the proposed modified electrode are in most cases superior to the previously reported modified electrodes. The average current measured and the precision estimated in terms of relative standard deviation (RSD%) for fifteen repeated measurements (n = 15) of 10.0 µmol L -1 of hydroxylamine at the applied potential of 170 mV on OBMWCNT-GCE were 0.107 ± 0.003 µA and 2.9% respectively.…”

“…Therefore, in this work, a moderate MWCNT value of 3 mL of MWCNT-DMF solution (1 mg mL -1 ) was selected for the fabrication of OBMWCNT-GCE. This value of MWCNT-DMF solution is significantly less than 15 µL that were used for fabrication of CGA-MWCNT-GCE, 42 but the sensitivity of hydroxylamine determination at OBMWCNT-GCE surface increases compared with that at a CGA-MWCNT-GCE. This result indicates that OB is an excellent mediator for electrocatalytic oxidation of hydroxylamine in comparison with CGA.…”

“…Therefore, various methods have been reported for the determination of low levels of hydroxylamine from industrial, environmental, and health viewpoints. [34][35][36][37][38][39][40][41][42][43][44] These include chromatography, 34,35 spectrophotometric 37 and electrochemical methods. 10,11,14,16,32,[38][39][40][41][42][43][44] In this regard, we had reported the preparation of a rutin multi-walled carbon nanotubes modified glassy carbon electrode (RMWCNT-GCE), 14 a coumestan derivative modified carbon paste electrode, 32 an indenedione derivative MWCNT-GCE (IMWCNT-GCE), 41 a chlorogenic acid MWCNT-GCE (CGA-MWCNT-GCE), 42 a 4-hydroxy-2-(triphenylphosphonio)phenolate MWCNT-GCE (HTP-MWCNT-GCE), 43 a ruthenium oxide nanoparticles, 44 and their applications in hydroxylamine determination.…”

Neste trabalho, a oxidação eletrocatalítica de hidroxilamina em um eletrodo de carbono vítreo modificado com "oracet blue" e nanotubos de carbono de paredes múltiplas (OBMWCNT-GCE) foi estudada. O potencial de pico de hidroxilamina em superfície OBMWCNT-GCE desloca em cerca de 320 e 335 mV para valores negativos, em comparação com aqueles em superfície MWCNT e superfície GCE ativada. Os parâmetros cinéticos para a oxidação de hidroxilamina na superfície modificada do eletrodo foram determinados por medidas de voltametria cíclica. A detecção amperométrica da hidroxilamina foi realizada em 170 mV em uma solução tampão de fosfato (pH 7,0), resultando em dois intervalos de resposta linear de 4,0-102,4 e 102,4-5820,9 µmol L -1 e limite de detecção de 0,7 µmol L -1 . A resposta amperométrica para a determinação de hidroxilamina provou ser reprodutível, rápida e estável. Finalmente, OBMWCNT-GCE foi aplicado com sucesso à determinação de hidroxilamina em duas amostras de água natural.In this work, the electrocatalytic oxidation of hydroxylamine on a glassy carbon electrode modified with oracet blue and multi-walled carbon nanotubes (OBMWCNT-GCE) has been studied. The peak potential of hydroxylamine at OBMWCNT-GCE surface shifts by about 320 and 335mV toward negative values compared with those at a MWCNT and activated GCE surface. Kinetic parameters for the oxidation of hydroxylamine at the modified electrode surface were determined by cyclic voltammetry measurements. The amperometric detection of hydroxylamine was carried out at 170 mV in a 0.1 mol L -1 phosphate buffer solution (pH 7.0) resulting in two linear response ranges of 4.0-102.4 µmol L -1 and 102.4-5820.9 µmol L -1 and the limit of detection of 0.7 µmol L -1 . The amperometric response for hydroxylamine determination proved to be repeatable, fast and stable. Finally, OBMWCNT-GCE was successfully applied to the hydroxylamine determination in two water natural samples.

In this research, we report the preparation of a high sensitive voltammetric sensor for electrocatalytic determination of hydroxylamine (HX) in the presence of thiosulfate (TS). We describe the synthesis and characterization of CdO nanoparticles (CdO/NPs) with transmission electron microscopy (TEM) and X‐ray diffraction (XRD) methods. At an optimum condition, the two peaks are separated ca. 0.58 and 0.92 V for HX and TS at the surface of the proposed sensor. Square wave voltammetry (SWV) of HX exhibited two linear dynamic ranges with a detection limit (3σ) of 0.06 µmol L−1. The propose sensor was used for determination of HX in water samples.

A Boron Doped Diamond Electrode Modified with Nano‐carbon Black for the Sensitive Electrochemical Determination of Chlorogenic Acid

An electrochemical method was developed for the sensitive determination of chlorogenic acid using a boron doped diamond electrode (BDDE) modified with nano‐carbon black (nano‐CB). The active surface areas were found to be 0.059 and 0.146 cm2 for the unmodified BDDE, and nano‐CB/BDDE, respectively. Compared with a BDDE, the nano‐CB/BDDE exhibited a well‐defined redox couple for chlorogenic acid. In addition, the plot of the peak current response changing from a square root to a linear dependence on scan rate is attributed to the transition from planar diffusion to surface behaviour. The anodic and cathodic peak separations (ΔEp) were 97 mV and 14 mV at BDDE and nano‐CB/BDDE, respectively. The decrease in ΔEp at the proposed electrode indicated that the process of chlorogenic acid was greatly accelerated. Square wave voltammetry (SWV) exhibited a dynamic range in which the current versus the concentration of chlorogenic acid were linear from 2.0×10−8 to 2.0×10−6 M with a LOD of 4.1×10−9 M (based on 3Sb/m). The nano‐CB modified BDDE provided improved electrochemical behavior, high electrocatalytic activity, high sensitivity and good reproducibility.
