Abstract
A high-performance liquid chromatography-tandem mass spectrometry method was developed for the determination of cyazofamid and its major metabolite 4-Chloro-5-(4-tolyl)-1H-imidazole-2-carbonitrile (CCIM) in oily samples. Samples were extracted with acetonitrile, which contained 1% acetic acid and cleaned-up with C18 and Florisil absorbents. Recoveries ranged from 75.91% to 109.85% with coefficients of variation from 5.14% to 10.69%. The limits of detection (LODs) and the limits of quantification (LOQs) were >0.0020 mg kg-1 and ≤0.0040 mg·kg-1, respectively, which were smaller than maximum residue levels established by Australia for oily samples. The proposed fragmentation pathway of cyazofamid and CCIM were discussed.

Nimesulide Determination on Carbon Black-Nafion Modified Glassy Carbon Electrode by Means of Adsorptive Stripping Voltammetry. Electrocatalysis (N Y) 2021.

Abstract
AbstractAdsorptive Stripping Voltammetric method for Nimesulide (NIM) determination was developed. As a working electrode, glassy carbon electrode (GCE) modified with carbon black and Nafion (CB-Nafion GCE) was used. All measurements were carried out in 0.1 M acetate buffer (pH 4.6). Conducted experiments allowed to optimize differential pulse voltammetry (DPV) instrumental parameters: sampling and waiting time ts = tw = 10 ms, step potential Es = 4 mV, and pulse amplitude ΔE = 50 mV. The best results were obtained for preconcentration potential and time equal to 400 mV and 20 s, respectively. Limit of detection was calculated and was equal to 0.14 µM for 20-s preconcentration time and 0.06 µM for 40-s preconcentration time. In order to prove the applicability of the developed method, concentration of nimesulide in pharmaceutical products was determined. Calculated recoveries were in the range 94–99%, which indicates that the method might be assumed as accurate. Coefficient of variation was equal to 5.0% (n = 7, NIM concentration 1 µM) Obtained results of NIM determination were in good agreement with the content declared by producers.

Abstract
A new, highly sensitive Adsorptive Stripping Voltammetric method for levodopa determination was developed. As a working electrode, the glassy carbon electrode (GCE) modified with carbon black (CB), RuO2·xH2O (RuO2) and Nafion was used (CB-RuO2-Nafion GCE). Levodopa signal obtained on the modified electrode was 12 times higher compared to GCE. During research, instrumental parameters were optimized: sampling time ts = 10 ms, waiting time tw = 10 ms, step potential Es = 5 mV and pulse amplitude ΔE = 50 mV. Preconcentration potential Eprec was equal to 0 mV. The best results were obtained in 0.025 M perchloric acid (approx. pH 1.4). Signal repeatability measured on the CB-RuO2-Nafion modified electrode for 0.2 µM of levodopa was equal to 2.1% (levodopa concentration 1 µM, n = 5). Linearity of the method was achieved in the concentration range from 1 to 8 µM. Limit of detection was equal to 17 nM. Recoveries calculated for pharmaceutical products and tap water measurements were in the range 102-105%, which confirms the accuracy of the developed. The applicability of the method was confirmed by analysis of pharmaceutical products and tap water samples. Based on obtained results, it might be concluded that the developed voltammetric method could be a useful tool in routine drug analysis.

Abstract
On account of the recalcitrant and highly toxicity of organonitrile substrates, traditional processes are limited by HCN poisoning thus inefficient. This article proposed a novel anaerobic fluidized bed reactor with electric field activation (AFBR-EFA) which had a 260-day continuous operation. The operation aims to explore the practicability of the enhanced reduction of isophthalonitrile (IPN), with emphasis on the optimum operation parameters and synergistic effect between electric field and anaerobic processes. The results showed that relatively higher voltage (1.0 V < V < 1.6 V) had a positive impact on reduction enhancement. High removal could be obtained at high initial concentration, low methanol dosage and short HRT which indicated that tolerance to shock loading was significantly enhanced in AFBR-EFA. Furthermore, EFA visibly motivated the enrichment of electrochemically active bacteria and various autotrophic IPN degradation-related species. The significantly efficient performance makes the potential for full-scale application of the AFBR-EFA markedly improved, particularly for treating hard-biodegraded contaminants.

Abstract
ABSTRACT In this paper, the square-wave adsorptive stripping voltammetric (SWAdSV) determination of the veterinary drug closantel using a renewable silver amalgam film electrode (Hg(Ag)FE) is presented. As observed in SWAdSV, closantel provided one well-shaped reduction peak suitable for analytical purposes at potential ca. -1.4 V in the Britton-Robinson (B-R) buffer at pH 7.0. At optimal conditions, the SWAdSV response of Hg(Ag)FE for determining closantel was linear over two concentration ranges of 5.0 × 10-8 to 2.0 × 10-7 mol dm-3 and 2.0 × 10-7 to 1.2 × 10-6 mol dm-3 with a detection limit of 1.1 × 10-8 mol dm-3. In addition, a relevance of the developed SWAdSV method was successfully verified by the quantitative analysis of closantel in the commercial formulation Closamectin Pour-On with satisfactory results (RSD = 5.8%, recovery = 101.8%). The results showed that the developed procedure can be adequate for screening purposes. Also, the electrochemical behavior of closantel was characterized by cyclic voltammetry, and it was found that closantel exhibited a quasi-reversible behavior with cathodic peak on the forward scan at ca. -1.4 V and anodic peak on the reverse scan at ca. -1.35 V vs. Ag/AgCl in B-R buffer, pH 7.0. As the obtained results showed that the electrode mechanism of closantel is controlled by the adsorption, the effect of adsorption was studied using the electrochemical impedance spectroscopy technique.
