Electrochemical performance of a new imidazolium ionic liquid crystal and carbon paste composite electrode for the sensitive detection of paracetamol

, 2020
A new ionic liquid crystal (ILC) bearing a biphenyl core and a terminal imidazolium moiety was synthesized which exhibited two enantiotropic smectic A mesophases having a wide phase range. Interestingly one of these mesophases exhibited the features of a

Electrochemical response of oligonucleotides on carbon paste electrode

Bioelectrochemistry, 2007
Electrochemical response of synthetic oligonucleotides with different DNA bases sequences was investigated to find relationships between a chain composition and a signal. All DNA mononucleotides present electroactivity at a carbon paste electrode yielding anodic peaks at potentials: 1.00 (GMP), 1.28 (AMP), 1.47 (TMP) and 1.53 V (CMP).

Comparative investigation on electrochemical behavior of hydroquinone at carbon ionic liquid electrode, ionic liquid modified carbon paste electrode and carbon paste electrode

Electrochimica Acta, 2007
Ionic liquid, 1-heptyl-3-methylimidazolium hexafluorophosphate (HMIMPF6), has been used to fabricate two new electrodes, carbon ionic liquid electrode (CILE) and ionic liquid modified carbon paste electrode (IL/CPE), using graphite powder mixed with HMIMPF6 or the mixture of HMIMPF6/paraffin liquid as the binder, respectively.

Carbon Nanotube Purification:  Preparation and Characterization of Carbon Nanotube Paste Electrodes

Analytical Chemistry, 2003
Paste electrodes have been constructed using single-wall carbon nanotubes mixed with mineral oil. The electrochemical behavior of such electrodes prepared with different percentages of carbon nanotubes has been compared with that of graphite paste electrodes and evaluated with respect to the electrochemistry of ferricyanide with cyclic voltammetry ...

A microscopic study on carbon paste electrodes

Electroanalysis, 1996
AbstractScanning electron microscopy has been used for observing the surface of several types of carbon paste electrodes in order to reveal the role of both pasting liquid and carbon powder on the formation of the carbon paste structure. The effect of pasting liquid was studied using carbon pastes prepared from RW‐B multicrystalline graphite powder and

Electrooxidation of methadone on carbon paste electrodes

Electrochimica Acta, 1989
Abstract The oxidation of methadone on carbon paste electrodes has been studied using voltammetric techniques under semi-infinite linear diffusion and hydrodynamic conditions. A simple “in situ” electrode pretreatment is proposed to obtain a good reproducibility of the current signal.

Hexacyanoferrate‐anion exchanger‐modified carbon paste electrodes

Electroanalysis, 1997
AbstractThe preparation of carbon paste electrodes (CPEs) modified with the hexacyanoferrate ion attached to synthetic hydrotalcite, a solid anion exchange resin Wofatit SBW and a liquid anion exchanger tris‐octylamine (TOA) used as pasting liquid, is described. Stability of the electrodes and their electrocatalytic properties were investigated.
