A simple, sensitive and selective differential pulse voltammetry method for determination of paracetamol on a bare (unmodified) boron-doped diamond film electrode has been developed. It was found by cyclic voltammetry that paracetamol provided the quasireversible wave with oxidation peak on the forward scan about +0.90 V and smaller reduction peak on the reverse scan at +0.68 V vs. Ag/AgCl. The...

Graphene oxide drop-casted on a platinum microelectrode was successfully changed to reduced graphene by using cyclic voltammetry method. The presence of an electrochemically layer the electrode proved scanning electron microscopy images, Raman and Fourier-transform infrared spectroscopy spectra. Cyclic linear sweep results indicated that modified with can be used as electrochemical sensor for d...

In this manuscript, the electrocatalytic oxidation of doxepin (DOX) was studied at a carbon ionic liquid electrode, fabricated using graphite, and the ionic liquid 1-octylpyridinium hexaflourophosphate (OPFP). The surface of the proposed electrode was characterized by scanning electron microscopy. Differential pulse voltammetry was applied as an analytical technique for quantification of sub-mi...

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...

the electrochemical behavior of nifedipine (i), nitrendipine(ii) and their photodegradation products has been studied by employing electrochemical techniques in chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (ppc) as supporting electrolyte. it has been shown that i and ii undergo in a 4e, 4h+ irreversible reduction reaction, while the reduction product, p...

“Cyclic voltammetry” is one of the most common electrochemical techniques, not only for electrochemists but also researchers in other fields. However, principles cyclic voltammetry are very complex; beginners and even experts may struggle with their application. Therefore, we explain fundamental Part 1 introduce practical issues associated recent trends such as fuel cells, capacitors, sensors 2...

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...

Investigation of the electrochemical behavior using cyclic voltammetry and detection of [Mn(2+)(thiophenyl-2-carboxylic acid)2 (triethanolamine)] with adsorptive stripping differential pulse voltammetry. The electrochemical behavior of a manganese(II) complex [Mn(2+)(thiophenyl-2-carboxylic acid)2(triethanolamine)] (A) was investigated using cyclic and differential pulse voltammetry in an aceta...
