Abstract

An analytical method for the determination of Flubendiamide (FBD) was investigated for the first time in this study using disposable pencil graphite electrodes (PGE). A detailed study of the electrochemical properties of FBD was carried out in phosphate buffer solution (PBS, pH 7.0). The results showed a well-defined reversible system result from the transformation of FBD to the corresponding hydroxyl-derivative. The results showed a linear range from 1 to 500 µM (R2 = 0. 9952), as well as detection limit of 0.53 µM. The PGE sensor was successfully applied for the detection of FBD in wastewater and white rice. [ABSTRACT FROM AUTHOR]

Abstract

4-Aminoquinoline including Hydroxychloroquine (HCQ), amodiaquine (AQ), Chloroquine (CQ) are a quinoline with an amino group at the 4th position with a basic side chain. They are generally used as antimalarial medications. HCQ and CQ are recommended by the World Health Organization on march 2020 the use as a possible treatment to coronavirus (COVID–19). Long-term of 4-aminoquinoline drugs administration can be associated with toxic side-effects on the outer retina and the retinal pigment epithelium. Therefore, their determination in biological samples is important. Several methods have been used for 4-Aminoquinoline compounds analysis, such as spectrophotometry, immunological, electrophoresis, chromatography and electroanalytical methods. Electrochemical methods are more preferable because they are simple, quick analysis and more sensitive performance. Up to now, numerous electrochemical methods have been used to detect those drugs. Nevertheless, the utilization of later techniques is limited. Therefore, this review describes different electrochemical sensors, which are used for 4-aminoquinoline electroanalysis in complex matrices such as pharmaceuticals and biological fluids. For this, the fundamental analytical performance of the chosen sensors is investigated. The selectivity and oxidation mechanisms for 4-aminoquinoline reported in the literature were discussed. Also, the application of these sensors for 4-aminoquinoline monitoring in biological and environmental samples is reported. [ABSTRACT FROM AUTHOR]
