The renewable glassy carbon annular band electrode in a highly sensitive normal pulse voltammetric determination of paracetamol with continuous wavelet transformation

Review—Voltammetric Sensors with Laterally Placed Working Electrodes: A Review

“…Nowadays, a lot of attention is paid to formation of the modification layer with the variety of carbon nanomaterials. 21 The titanium electrodes are susceptible to oxidation in atmospheric air or in other oxidizing environments. To enhance its applicability in electrochemistry the electrode is often covered with polycrystalline platinum deposit.…”

“…62 SAS are adsorbed on the electrode surface decreasing its area, what in turn leads to a considerable signal decrease 1,20 and difference in the absolute values of the peak currents in the supporting electrolyte and studied samples containing organic matter (OM) and SAS. 63 Moreover, they may distort the analytical signal (peak or wave shape) 21 or cause its complete deterioration. 2 Due to the natural abundance of SAS in the variety of samples and the abovementioned drawbacks in voltammetric measurements, the appropriate sample pretreatment is required.…”

“…19 It is also the driving force in a search for alternative sensors, which would utilize mercury in an infinitesimal amount or in a safe form of an amalgam. 14,20 The increasing number of researches focus on development of new, nontoxic electrode materials, including metals, 5 ceramics 2 and carbon 21 compounds, which offer similar or better functioning in electroanalytical applications.…”

Structural and electrochemical characterization of carbon electrode modified by multi-walled carbon nanotubes and surfactant

“…Electrode material based on carbonaceous compounds has been widely applied in electrochemistry and electroanalysis as working electrode due to their special properties including low resistivity, chemical inertness, and unique surface chemistry, which make them a proper choice to determine a wide range of substances in electrocatalytic area [1][2][3][4][5][6][7]. Also carbon electrodes (CEs) have the advantage of having a larger hydrogen overvoltage rather than metals [8].…”

Electrochemical Sensor Based on Nanocomposite of Multi-Walled Carbon Nanotubes / TiO2Nanoparticles in Chitosan Matrix for Simultaneous and Separate Determination of Dihydroxybenzene Isomers

“…The carbon nanotubes (CNTs), among carbon structures including glassy carbon, carbon paste, screen-printed carbon, carbon fiber, carbon nanotubes, have been explored and exploited widely with applications from the electronic to the biomedical purposes. [1][2][3][4] It is a promising material in the fields of sensors, highperformance nanocomposites, semiconductor devices, energy conversion devices, etc. 5,6 because of its nano-scale structure, high mechanical strength, high specific surface area and extraordinary electronic properties.…”
