Linear scan voltammetry (LSV), differential pulse voltammetry (DPV) and voltammetry with adsorptive accumulation (AAV) at a glassy carbon paste electrode (GCPE) based on mixing glassy carbon spherical microparticles with an organic pasting liquid were used for the determination of trace amounts of carcinogenic 1-nitropyrene (1NP) (the limit of determination around 2.10 mol L for LSV and 2.10 mo...

The reaction volumes (_H '^), corresponding to the volume change for the half-cell reactions for a series of M(ttcn)23+/2+ couples were measured by using cyclic voltammetry at elevated pressures. The A V }$ values reflect the changes in the bond length between M and ligands accompanying the changes in the oxidation state of M from 3+ to 2+. The values of the estimated A V ^ are in the order of ...

A new Schiff base 2-aminothiophenol furfural self assembled monolayer (SAM) has been fabricated on a bare gold electrode as a novel sensor for determination of dopamine. Electrochemical impedance spectroscopywas utilized to investigate the properties of the Au 2-aminothiophenol furfural self assembled monolayermodified electrode (Au ATF SAM-ME) using the [Fe(CN)6]3-/4- redox couple. The electro...

MnO2 metal oxide electrode material is synthesized by simple electrodeposition method on stainless steel substrate. The crystal structure and surface morphological characterizations of the obtained are carried out using X-ray diffraction (XRD) technique Field Emission-Scanning Electron Microscopy (FE-SEM) respectively. FE-SEM micrographs show highly porous well developed interconnected uniform ...

Surfactant modified carbon nanotube paste electrode is prepared as electrochemical sensor with high sensitivity responding to mitoxantrone (MTX). Electrochemical oxidation of MTX is investigated in buffered solution by cyclic voltammetry that is found very sensitive method for detection of MTX. It is shown that the sodium dodecyl sulfate modified carbon nanotube paste electrode (SDSMCNTPE) give...
