Electrochemical determination of sildenafil citrate as standard, in tablets and spiked with human serum at gold and cystein modified gold electrode
(Elsevier Science Sa, Lausanne, 2016)
Nonmedical use of sildenafil citrate (SC) requires new methods for drug determination in human serum and in tablets. SC as standard and in Sildena (R) tablets is determined by square wave voltammetry (SWV) in 0.1 M H2SO4 ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier B.V., 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Journal of Electroanalytical Chemistry, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Electrochemical behavior of esomeprazole: Its determination at Au electrode as standard and in injection powder combined with the study of its degradation
(Elsevier Science Sa, Lausanne, 2019)
Esomeprazole is the most effective of the proton-pump inhibitors for the acid-related diseases and at first was examined for the electroanalytical purposes. The drug standard and as a content of injection powder was ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Challenges in determining the electrochemically active surface area of Ni-oxides in the oxygen evolution reaction
(Elsevier B.V., 2022)
Thin films of Ni-oxy-hydroxides of different composition and thickness were electrochemically grown on Ni foil electrode: hydrated α-phase, anhydrous β-phase, and two mixed α- and β-phase electrodeposited by potential ...
Application of the general theory of disperse deposits formation in an investigation of mechanism of zinc electrodeposition from the alkaline electrolytes
(Elsevier, 2017)
In this study, mechanism of electrodeposition of zinc from the alkaline electrolytes has been investigated using the general theory of disperse deposits formation. The exchange current densities in the range 18.4-88 mA ...
Voltammetric behavior of solifenacin succinate on gold, glassy carbon and boron-doped diamond electrodes: Stability testing and determination
(Elsevier B.V., 2024)
The anticholinergic drug, solifenacin, is frequently used for the treatment of the urological tract for urinary incontinence, and urinary frequency. The development of reliable and effective solifenacin electrochemical ...
Oxygen reduction on iron. Part VII. Temperature dependence of oxygen reduction on passivated iron in alkaline solutions
(Elsevier Science Sa, Lausanne, 1995)
The temperature dependence of the kinetics of O2 reduction was studied on passivated Fe in NaOH solutions having a concentration ranging from 0.010 to 1.0 mol dm-3 and in the temperature range from 2 to 42 °C. The apparent ...
Electrocatalysis by nanoparticles - Oxygen reduction on Ebonex/Pt electrode
(Elsevier, 2006)
The oxygen reduction reaction was studied in 0.5 mol dm-3 HClO4 solution on an electrode based on Ebonex-supported platinum electrocatalyst applied on rotation Au disk electrode (Au/Ebonex/Pt). Pt catalyst was prepared by ...
