Voltammetric Determination of Favipiravir Used as an Antiviral Drug for the Treatment of Covid‐19 at Pencil Graphite Electrode. Electroanalysis, 35(4). https://doi.org/10.1002/elan.2022002951040-03971521-4109https://doi.org/10.1002/elan.202200295https://hdl.handle.net/20.500.12428/5454This work describes the sensitive voltammetric determination of favipiravir (FAV) based on its reduction for the first time with a low-cost and disposable pencil graphite electrode (PGE). In addition, the determination of FAV was also performed based on its oxidation. Differential pulse (DP) voltammograms recorded in 0.5 M H2SO4 for the reduction of FAV show that peak currents increase linearly in the range of 1.0 to 600.0 μM with a limit of detection of 0.35 μM. The acceptable recovery values (98.9–106.0 %) obtained from a pharmaceutical tablet, real human urine, and artificial blood serum samples spiked with FAV confirm the high accuracy of the proposed method.eninfo:eu-repo/semantics/closedAccessCOVID-19Differential Pulse VoltammetryFavipiravirPencil graphite electrodeArticle35410.1002/elan.202200295Q2WOS:0008844406000012-s2.0-8514207083036712592
