“…PC-based electrodes have been widely used in voltammetric studies because of low cost, availability, stability, and easy modification of the carbon morphology. There are a number of carbon-based electrodes such as GCE, carbon nanotubes (CNTs), and most recently, graphene. , Moreover, the proposed PC 900 -modified GCE-based sensor indeed exhibits superior analytical performances with a wide linear range and LOD compared to other previously reported electrode materials for electrochemical detection of 4-NA, as listed in Table . ,− …”

In this study, Liquidambar formosana tree leaves have been used as a renewable biomass precursor for preparing porous carbons (PCs). The PCs were produced by pyrolysis of natural waste of leaves after 10% KOH activation under a nitrogen atmosphere and characterized by a variety of state-of-the-art techniques. The PCs possess a large surface area, micro-/mesoporosity, and functional groups on its surface. A glassy carbon electrode modified with high PCs was explored as an efficient binder-free electrocatalyst material for the voltammetric determination of nitro isomers such as 3-nitroaniline (3-NA) and 4-nitroaniline (4-NA). Under optimal experimental conditions, the electrochemical detection of 3-NA and 4-NA was found to have a wide linear range of 0.2–115.6 and 0.5–120 μM and a low detection limit of 0.0551 and 0.0326 μM, respectively, with appreciable selectivity. This route not only enhanced the benefit from biomass wastes but also reduced the cost of producing electrode materials for electrochemical sensors. Additionally, the sensor was successfully applied in the determination of nitro isomers even in the presence of other common electroactive interference and real samples analysis (beverage and pineapple jam solutions). Therefore, the proposed method is simple, rapid, stable, sensitive, specific, reproducible, and cost-effective and can be applicable for real sample detection.

“…The silver particles could not only improve the sensitivity of detection for some organic compounds, but also could be applied to the catalysis of their electrochemical reaction [ 36 ]. The electrochemical reduction of thiamethoxam based on reduction of its nitro group via four electron process to generate the hydroxylamine derivative [ 37 , 38 , 39 , 40 ]. In this context, we proposed here a novel electrochemical approach for TXM analysis that based on the electrodeposition of silver particles on graphite electrode (Ag@GrCE) using chronoamperometry.…”

The purpose of this paper is the electrodeposition of silver particles on graphite electrode (Ag@GrCE) using chronoamperometry and the use of this electrode for the determination of thiamethoxam. The electrode was prepared by chronoamperometry and characterized by X-Ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), EDX analysis and electrochemical impedance spectroscopy. The obtained electrode exhibits excellent electrocatalytic activity toward thiamethoxam reduction. The voltammetric response was linear as function of TXM concentration with a limit of detection around to 1.92 × 10 −6 mol L −1 . The proposed electrode was successfully used to analyze thiamethoxam residue in some food samples including orange and tomato juices.

Current Trends in Analytical Methods for the Determination of Hydroxychloroquine and Its Application as Treatment for COVID‐19

Hydroxychloroquine (HCQ) is a drug indicated in rheumatology for the treatment of rheumatoid arthritis and systemic lupus erythematosus for its anti‐inflammatory and immunomodulatory properties. Many countries such as Morocco have recommended the use of HCQ for the treatment of COVID‐19 infection. This medication is responsible for severe acute poisoning. Therefore, Hospital laboratories have a fundamental role in affirming the diagnosis and assessing the severity of intoxication by measuring HCQ, carried out in the urine and preferably in whole blood. The analytical techniques used are essentially chromatographic. Unfortunately, these reference methods for forensic analyzes are difficult to adapt to emergency due to their delay in reporting results.
