Electrocatalytic behaviour of carbon paste electrode modified with iron(II) phthalocyanine (FePc) nanoparticles towards the detection of amitrole

Preparation and characteristic of cobalt phthalocyanine modified carbon paste electrode for bisphenol A detection

“…While the excess of CoPc particles surrounded the surface of graphite powder will decrease the efficient area of electrode. The same phenomenon was obtained with the studies of electrocatalytic oxidation of amitrole at nanoFePc-CPE [35] and ss-DNA at CoPc modified CPE [36]. Hence a CoPc (4%, m/m) modified carbon paste electrode was used throughout this work.…”

Electrochemical Sensing of Catecholamines at the Water/ 1,6‐Dichlorohexane Interface

“…From the values obtained it was possible to conclude that AA has a more pronounced interference in the determination of NAH + when compared to DAH + , since NAH + transfer occurs more close to the positive limit of the potential window. The magnitude of the selectivity coefficient values obtained [61] reveal that AA does not significantly interfere in the determination of DAH + at the water/DCH interface, which is in agreement with the reports of Shao et al [41] and Arrigan et al [42][43][44] for the determination of DAH + at the water/DCE interface. In the case of NAH + , the magnitude of the selectivity coefficient obtained [61] suggests that AA interferes moderately in the determination of this molecule.…”

Electrocatalytic voltammetric determination of guanine at a cobalt phthalocyanine modified carbon nanotubes paste electrode

“…This is because the sites for catalysis and adsorption increased with the increase of CoPc percentage in the modified electrode, while the excess of CoPc particles surrounded the surface of nanotube powder will decrease the efficient area of the electrode. The same phenomenon was observed in the case of electrocatalytic oxidation of amitrole at nano-FePc-CPE [37] and ssDNA at CoPc modified CNTPEs [32]. Hence a CoPc (1%, w/w) modified carbon nanotubes paste electrode was used throughout this work.…”
