Differential pulse voltammetric determination of eugenol at a pencil graphite electrode
Materials Science and Engineering C, 2016In this study, the electrochemical behavior of eugenol, a widely used herbal drug, was investigated at a pencil graphite electrode (PGE). A low-cost, disposable, sensitive and selective electrochemical sensor is proposed for the determination of eugenol by recording its differential pulse voltammograms in Britton-Robinson buffer solution containing 0.1

Sensitive Voltammetric Determination of Niclosamide at a disposable pencil graphite electrode
Electrochimica Acta, 2014Abstract Niclosamide (NA), an effective drug against tapeworm infections, was electrochemically studied using a pencil graphite electrode (PGE). A low-cost sensitive and selective procedure was developed for determination of NA by recording differential pulse voltammograms of NA in pH 7.0 Britton-Robinson buffer solution containing 0.1 M KCl and 30 ...

Biosensing based on pencil graphite electrodes
Talanta, 2018Pencil leads have been increasingly used as electrode material in electrochemical applications. Commonly denominated as pencil graphite electrodes (PGE), they represent a viable alternative to other standard electrodes due to their comparable electrical properties but mainly for their low cost and availability, enabling disposable applications.

Sensitive Electrochemical Determination of Trifluralin at a Disposable Pencil Graphite Electrode
Electroanalysis, 2021AbstractA sensitive differential pulse (DP) voltammetric method has been proposed for the determination of trifluralin (TFA) based on both its reduction and oxidation at a disposable pencil graphite electrode (PGE). DP voltammograms recorded under optimized conditions show that oxidation and reduction peak currents increased linearly in the range from ...

Electrocatalytic oxidation of NADH using a pencil graphite electrode modified with quercetin
Colloids and Surfaces B: Biointerfaces, 2013In the present study, the electrocatalytic oxidation of reduced β nicotinamide adenine dinucleotide (NADH) was investigated using a pencil graphite electrode modified with quercetin (PGE/QH(2)). The PGE/QH(2) was prepared through two steps: (i) the pre-treatment of PGE at 1.40 V vs.

Comprehensive Study of the Resistance of Pencil-Stroked Graphite on Paper Electrodes
The Physics Educator, 2022In this paper, we comprehensively study the electrical resistance of pencil-stroked graphite electrodes, which is a cheap electrical conductor. Thin graphite on paper (GOP) electrodes were manually fabricated by unidirectionally stroking rectangular areas defined by grids on graph paper, allowing the physical dimensions of the layer to be accurately ...

Voltammetric Study of Aminopurines on Pencil Graphite Electrode in the Presence of Copper Ions
Electroanalysis, 2010AbstractElectrochemical oxidations of aminopurines (adenine, 2‐aminopurine, 2,6‐diaminopurine) and their complexes with Cu(I) on a pencil graphite electrode were investigated by means of linear sweep voltammetry (LSV) and elimination voltammetry with linear scan (EVLS). The anodic process of the Cu(I)‐aminopurine complex, corresponding to the oxidation
