“…Among these electrodes, the PGE attracts great attention due to its many advantageous properties. These features can be listed as follows; disposability, low-priced, pretty reactive, renewable surface, less toxicity, extensive potential range, well mechanical rigidity, and easily available [16][17][18][19][20][21][22].…”

The proposed study describes a novel and disposable voltammetric sensor that designed for the sensitive determination of celestine blue (CelsB) using a pencil graphite electrode (PGE). The electrochemical characterization study of the designed sensor was performed by recording the cyclic voltammograms (CVs) and electrochemical impedance (EI) curves in 5.0 mM of Fe(CN)63-/4- including 0.10 M of KCl, and compared with the other carbon-based electrodes such as carbon paste (CPE) and glassy carbon (GCE) electrodes. The electrochemical behaviour of CelsB was examined at different carbon-based electrodes including PGE, CPE, and GCE by the cyclic voltammetric (CV) method. The recorded CVs showed that the remarkable response obtained at PGE toward oxidation of CelsB. Moreover, the PGE shows a wide linear range (4.0 − 150 μM) and detects the CelsB with a notable limit of detection (1.21 μM). In addition, the results from the interference studies proved that the PGE enables selective voltammetric determination of CelsB in presence of various species. A feasibility study for CelsB sensor was also tested on tap water and cherry apple juice samples and the recovery values obtained between 96.2 − 103 % with high precision and accuracy indicated that the PGE shows an acceptable and good applicability to real samples.

In this study, the electrochemical properties of nepafenac, used after eye surgery operations, were investigated on a disposable pencil graphite electrode. Cyclic and square wave voltammetry techniques were used to investigate the electrochemical properties of nepafenac. Two peaks at potentials of approximately +0.33 V and +1.03 V in the anodic direction and two peaks at potentials of approximately +0.29 V and +0.08 V in the cathodic direction were observed on the surface of the disposable pencil electrode in acetate (pH 4.8) medium with the cyclic voltammetry technique. The analytical performance of the developed voltammetric technique had good linearity in the concentration range of 0.30 µM to 3.5 µM at pH 4.8. The LOD value of this voltammetric method in acetate (pH 4.8) medium was calculated as 0.035 µM (8.90 ng mL−1). For reproducibility, the relative standard deviation (RSD) values for Ia and IIa anodic peak current/potential were found to be 1.45%/0.43% and 1.28%/0.25%, respectively. The voltammetric method was successfully applied to urine and pharmaceutical preparations and the results were compared with the spectrophotometric method.
