“…In the second peak, the slope is calculated to be 0.060 (the slope of the second anodic peak), the value of αn will be equal to 0.98, and the number of electrons is estimated to be 1.97 (≈ 2.0 electron). All the obtained results agree with the previously reported results concerning the oxidation of the pyrrolidine ring [ 16 , 32 ].…”

A novel voltammetric platform based on pencil graphite electrode (PGE) modification has been proposed, containing bimetallic (NiFe) Prussian blue analogue nanopolygons decorated with electro-polymerized glyoxal polymer nanocomposites (p-DPG NCs@NiFe PBA Ns/PGE). Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and square wave voltammetry (SWV) were utilized to investigate the electrochemical performance of the proposed sensor. The analytical response of p-DPG NCs@NiFe PBA Ns/PGE was evaluated through the quantity of amisulpride (AMS), one of the most common antipsychotic drugs. Under the optimized experimental and instrumental conditions, the method showed linearity over the range from 0.5 to 15 × 10−8 mol L−1 with a good correlation coefficient (R = 0.9995) and a low detection limit (LOD) reached, 1.5 nmol L−1, with excellent relative standard deviation for human plasma and urine samples. The interference effect of some potentially interfering substances was negligible, and the sensing platform demonstrated an outstanding reproducibility, stability, and reusability. As a first trial, the proposed electrode aimed to shed light on the AMS oxidation mechanism, where the oxidation mechanism was monitored and elucidated using the FTIR technique. It was also found that the prepared p-DPG NCs@NiFe PBA Ns/PGE platform had promising applications for the simultaneous determination of AMS in the presence of some co-administered COVID-19 drugs, which could be attributed to the large active surface area, and high conductivity of bimetallic nanopolygons.

Cathodes for supercapacitors with enhanced capacitive performance are prepared using MnO2 as a charge storage material and carbon nanotubes (CNT) as conductive additives. The enhanced capacitive properties are linked to the beneficial effects of catecholate molecules, such as chlorogenic acid and 3,4,5-trihydroxybenzamide, which are used as co-dispersants for MnO2 and CNT. The dispersant interactions with MnO2 and CNT are discussed in relation to the chemical structures of the dispersant molecules and their biomimetic adsorption mechanisms. The dispersant adsorption is a key factor for efficient co-dispersion in ethanol, which facilitated enhanced mixing of the nanostructured components and allowed for improved utilization of charge storage properties of the electrode materials with high active mass of 40 mg cm−2. Structural peculiarities of the dispersant molecules are discussed, which facilitate dispersion and charging. Capacitive properties are analyzed using cyclic voltammetry, chronopotentiometry and impedance spectroscopy. A capacitance of 6.5 F cm−2 is achieved at a low electrical resistance. The advanced capacitive properties of the electrodes are linked to the microstructures of the electrodes prepared in the presence of the dispersants.

“…As a consequence of the limitations of conventional wastewater treatment plants in removing antibiotics, several efforts are being made to improve the removal ratio of antibiotics, such as advanced oxidation processes (AOPs) by forming highly reactive hydroxyl radicals (•OH), especially electrochemical oxidation (EO) (Marcelino et al 2015). EO process has proved to be an effective and versatile technology for the treatment of a wide range of contaminants (Hems et al 2016;Moreira et al 2017;Chang et al 2020;Novak Jovanovićet al 2020). In electro-oxidation, pollutants can be removed by (i) direct electrolysis, where pollutants exchange electrons directly with the anode surface without involvement of other substances, or (ii) indirect electrolysis, where organic pollutants do not exchange electrons directly with the anode surface but rather through the mediation of some electroactive species regenerated there, which act as intermediaries for electrons shuttling between the electrode and the organic compounds (Panizza & Cerisola 2009).…”

Antibiotic residues may be very harmful in aquatic environments, because of limited treatment efficiency of traditional treatment methods. An electrochemical system with Ti-based SnO2-Sb-Ni anode was developed to degrade a typical antibiotic chloramphenicol (CAP) in water. The electrode was prepared by sol-gel method. The performance of electrode materials, impact factors and dynamic characteristics were evaluated. The Ti-based SnO2-Sb-Ni electrode was compact and uniform by the characterization of SEM and XRD. The electrocatalytic oxidation of CAP was carried out in a single-chamber reactor by using Ti-based SnO2-Sb-Ni electrode. For 100 mg L−1 CAP, the CAP removal ratio of 100% and the TOC removal ratio of 60% were obtained at the current density of 20 mA cm−2 and in neutral electrolyte at 300 min. The kinetic investigation has shown that the electro-oxidation of CAP on Ti-based SnO2-Sb-Ni electrode displayed pseudo first-order kinetic model. Free radical quenching experiments presented that the oxidation of CAP on Ti-based SnO2-Sb-Ni electrode resulted from the synergistic effect of direct oxidation and indirect oxidation (·OH and ·SO4−). Doping Ni on the Ti/SnO2-Sb electrode for CAP degradation was presented in this paper, showing its great application potential in the area of antibiotic and halogenated organic pollutants degradation.
