“…where E pa/2 represents the potential at which I ¼ I pa/2 , v is the scan rate, and D is the diffusion coefficient, determined by chronocoulometry as described next. Based on these experimental results and the most important reports in the literature, 5,6,52 4C). Based on the slopes of the linear relationship between Q and t 1/2 , A was calculated as 0.682 cm 2 for 3D GR/b-CDA/GCE, which is over 10 times that obtained for bare GCE (0.060 cm 2 ).…”

“…Using electroactivity, MD has also been investigated and determined conveniently by electrochemical methods. [3][4][5] A key role played in electrochemical detection should be the modied electrode materials, which determines, to a large extent, the sensitivity and speed of response. Although electrochemical detection of MD using modied electrodes such as a multi-walled carbon nanotube (MWCNT) modied gold electrode 6 and an electrochemically reduced graphene (GR) modied glassy carbon electrode (GCE) 7 have been reported, the sensitivity and detection limit are still potential obstacles to practical applications.…”

“…The electrode process of midecamycin, another macrolide with similar molecular structure, was discussed previously [45][46][47] and it was attributed to the oxidation of aldehyde group on the macrocycle in the molecule. Similarly, it was estimated that the anodic peak observed for spiramycin was obtained by the oxidation of the aldehyde group on the molecule to a carboxylic acid by losing two electrons.…”

Herein, an adsorptive stripping linear sweep voltammetric technique was described to determine spiramycin, a macrolide antibiotic, using a carboxylic multiwalled carbon nanotubes modified glassy carbon electrode. The main principle of the analytical methodology proposed was based on the pre-concentration of spiramycin by open-circuit accumulation of the macrolide onto the modified electrode surface. As a result of the adsorption affinity of spiramycin to the modified surface, the sensitivity of the glassy carbon electrode was significantly increased for the determination of spiramycin. The electrochemical behavior of spiramycin was evaluated by cyclic voltammetry and the irreversible anodic peak observed was measured as an analytical signal in the methodology. The proposed electrochemical sensing platform was quite linear in the range of 0.100-40.0 µM of spiramycin concentration with a correlation coefficient of 0.9993. The limit of detection and the limit of quantification were 0.028 and 0.094 µM, respectively. The intra and inter-day repeatability of the proposed sensor was within acceptable limits. Finally, the applicability of the electrochemical methodology was examined by determining the drug content of chicken egg samples spiked with spiramycin standard. A rapid and easy extraction technique was performed to extract spiked spiramycin from the egg samples. The extraction technique followed had good recovery values between 85.3 ± 4.0 and 93.4 ± 1.9%.

“…For the five concentrations, the amphetamine oxidation began at a potential 50 mV more negative than the potential at which gold oxide formation occurs. 14,15,18 After the first cycle, the anodic currents of the electro-oxidation of A strongly decreased with the cycling, which was attributed to poisoning of the electrode surface by the adsorption of their amine group. It seems that amphetamines were strongly adsorbed on the gold electrode and that the gold oxide enabled their oxidation.…”

The catalytic abilities of gold electrode were tested for the quantitative determination of amphetamine (A) and 3,4-methylenedioxy-N-methylamphetamine (MDMA) standards by their oxidation using cyclic voltammetry (CV). The value of the oxidative currents of A and MDMA standards at 0.80 V vs. SCE in 0.05 M NaHCO3 at the scan rate of 50 mV/s is linear function of concentration in range of 110.9-258.9 mM and 38.7-229.2 mM, respectively. Square wave voltammetry (SWV) revealed linear increase of current with concentration of MDMA (range 30.9-91.6 mM) and thus quantitative determination of amphetamine derivates. SWV analysis is successfully performed in spiked urine samples as well. A and MDMA in the presence of sucrose and as a content in illegally produced tablets were also analyzed. The voltammetric determination of A and MDMA derivatives using CV and SWV at gold electrode is a rapid, selective and simple procedure and its accuracy was confirmed with reference method, high performance liquid chromatography (HPLC). The spiked urine samples analysis offers additional possibility for the rapid detection of A and MDMA in human urine
