A theoretical analysis of reversible and quasireversible electrode reactions a dissolved redox couple under conditions the novel technique differential square-wave voltammetry (DSWV) is presented. The recently introduced as hybrid form between pulse (DPV) (SWV) two most advanced competitive pulse-form voltammetric techniques for purpose unifying their advantages further advancing both in terms ...

A theoretical study of an electrode mechanism where the reaction (E) is preceded by a chemical that takes place solely at surface (Chet) presented under conditions square-wave voltammetry (SWV). Rigorous mathematical solutions in form integral equations derived means Laplace transforms are for concentration all species involved mechanism, yielding explicit recurrent formulas simulation voltamme...

Electrochemical methods, specifically square wave voltammetry (SWV) offer fast, portable, and quantitative screening for antioxidant levels lipid degradation in consumer products. Initial studies within our research group utilized benzene as the non-polar component solvent systems analysis. In order to explore additional applications of SWV, less hazardous that maintain or improve on previous f...

In this theoretical work, we present for the first time voltammetric results of a surface multistep electron transfer mechanism that is associated with a preceding chemical reaction that is linked to the first electron transfer step. The mathematical model of this so-called “surface CEE mechanism” is solved under conditions of square-wave voltammetry. We present relevant set of results portrayi...

We report a simple and inexpensive electrochemical assay using a custom built hand-held potentiostat for the identification of explosives. The assay is based on a wipe test and is specifically designed for use in the field. The prototype instrument designed to run the assay is capable of performing time-resolved electrochemical measurements including cyclic square wave voltammetry using an embe...

The electrochemical reduction of the antidepressant drug fluoxetine was investigated by cyclic, linear sweep, differential pulse and square wave voltammetry using a hanging mercury drop electrode in alkaline buffer solution in water and in a water/acetonitrile mixed solvent. Cyclic voltammograms in aqueous solution showed very strong adsorption of fluoxetine on the electrode with formation of a...

A simple and rapid electrochemical method for the determination of atorvastatin in pharmaceutical preparations was developed. The anodic peak at 1.07 V obtained in a buffer on glassy carbon electrode was used for analysis. The peak current and peak potential depends on pH, scan rate and initial potential. Decrease of the anodic peak with increasing pH, as well as deviations from linear plots of...
