The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...

A new sensitive, selective and nonexpensive electrochemical sensor was developed for electrocatalyticdetermination of glutathione (GSH)in pharmaceutical and biological samples. GSH is a tripeptide thiol present in all eukaryotic and probiotic cells. A voltammetric studyof GSH has been carried out at the surface of carbon paste electrode modified with multiwall carbon nanotubes(MWCNTPE) in the p...

Voltammetry studies of electrodeposition are growing rapidly. Yet, relations for the analysis reactions in voltammetry remain relatively obscure literature. The existing cyclic and square wave their limitations discussed to increase awareness. A retrospective is performed demonstrate impact model selection improving behavior with voltammetric data. repository models proposed further familiarity...

A novel electrochemical sensor for testosterone detection has been prepared by the chemical modification of a gold electrode (AuE). For modification, specific polyurethane (PU) films were synthesized from hexamethylene diisocyanate, olivetol, polyethylene glycol-100 (PEG100) and β-cyclodextrin. The PUs investigated as selective films, used to coat AuE surface at different concentrations thickne...

We report here on differential linear scan voltammetry, DLSV, that combines the working principles of linear scan voltammetry, LSV, and the numerous existing pulsed voltammetry techniques. DLSV preserves the information from continuous interrogation in voltage and high accuracy that LSV provides about electrochemical processes, and the much better sensitivity of differential pulsed techniques. ...
