“…This electrode has many advantages over other solid electrodes, such as disposability, extremely low cost, commercially readily available, mechanical rigidity, ease of modification, no long‐time and hard polishing steps, and providing a renewable surface [ 34 , 35 , 36 , 37 , 38 ]. Therefore, PGEs have been extensively used in the electrochemical determination of many pharmaceutical compounds [ 39 , 40 , 41 , 42 , 43 ].…”

This 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 H 2 SO 4 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.

“…The remarkable detection sensitivity and e ciency of an electrochemical sensor are mostly dependent on the electrocatalytic activity of the electrode and modi cation materials. Recently, pencil graphite rods have been frequently used as an e cient electrode material because the obtained pencil graphite electrodes (PGEs) offer some advantages such as disposability, low cost, mechanical rigidity, simplicity, commercial availability, and ease of surface modi cation over other carbon-based or solid electrodes [12][13][14][15]. In addition, a large number of nanomaterials have been utilized in the preparation of modi ed electrodes and the construction of electrochemical sensors for signal ampli cation [16].…”

“…However, GCE and CPE involve laborious and time-consuming hard cleaning and surface polishing or preparation steps at the end of each measurement as well, and they have a high cost compared to PGE. SPCE is disposable, but its surface is not as renewable as in PGE, and it is also more expensive than PGE [12]. Compared with these traditional electrodes, the advantageous PGE has not been used in the studies carried out for the electrochemical determination of SBT yet.…”

This study describes a simple, highly sensitive, and cost-effective electrochemical determination of salbutamol (SBT) at a disposable pencil graphite electrode modi ed with na on/functionalized multiwalled carbon nanotubes composite material (Nf/f-MWCNTs/PGE). The electrochemical response of SBT at this modi ed electrode was investigated by both differential pulse voltammetry (DPV) and cyclic voltammetry (CV) techniques. The voltammetric measurements con rmed that the combination of f-MWCNTs with Nf shows remarkable electrocatalytic activity on the oxidation of SBT due to a synergistic effect of Nf via electrostatic interaction and f-MWCNTs via excellent conductivity and large speci c surface area. DPV results show that the composite electrode gives two linear ranges of 0.10-17.5 µM and 17.5-100 µM with a detection limit (LOD) of 0.027 µM SBT. Moreover, the studies of some potential interferants show that there is no signi cant interference in the determination of SBT. The proposed procedure was successfully applied to determine SBT in tube-and syrup-type pharmaceutical formulations and acceptable results were obtained with high accuracy and precision. Moreover, the proposed sensor displays good intraday and interday precision for the voltammetric determination of SBT..
