A voltammetric electronic tongue to classify five different types of edible oil samples is described in this study. The standard three-electrode configuration composes the sensor array: gold electrode, platinum electrode and saturated calomel electrode. Using cyclic voltammetric measurement, respectively, on five different types of edible oil samples (peanut oil, corn oil, soybean oil, sesame o...

Anionic detergents have been shown to lower markedly the differential-pulse voltammetric peak currents obtained for 12-molybdophosphate and 12molybdosilicate in aqueous solutions, but when ethanol water or acetone water (1 + 1 V / V ) solutions are used there is no interference. Static differential-pulse voltammetric and flow injection voltammetric procedures have been developed for the determi...

Electrochemistry of lercanidipine (LCN) was investigated and its optimal conditions were evaluated based on the irreversible and diffusion-controlled electrochemical oxidation signal (+ 0.93 V) of a carbon paste electrode (CPE) versus Ag/AgCl in Britton Robinson buffer (BR) and ethanol mixture of pH 4.5. Electrochemical determination was performed by square wave anodic adsorptive stripping volt...

A Chinese yellow wine classification method is proposed based on chemometric analysis of voltammogram of copper electrode. The main components in Chinese yellow wine are alcohol, amino acids and carbon hydrates. In strong alkaline solution copper electrode shows rich voltammetric responses to these components. Principal component analysis is employed to analyse voltammetric response of copper e...

A computerized electrochemical detection system for application after HPLC, provided with a cyclic voltammetric oxidative and reductive module, is described for the on-line qualitative determination of electroactive antineoplastic agents and metabolites in urine samples, collected from cancer patients, following intravenous administration.The application of two cyclic voltammetric detection mod...

There are numerous examples in the literature of amphiphilic molecules which, when adsorbed onto mercury electrodes, undergo electric-field-induced transitions between different molecular conformations. In general, very sharp and reversible voltammetric features associated with these transitions are observed when the electrode potential is scanned in the negative direction, typically over the r...
