چکیده

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 figures merit analytes interest are necessary. To this extent, ethanol was selected polar under 7th principle green chemistry (use renewable feedstocks). replace species (benzene), four candidates were identified 5th (safer solvents auxiliaries) including diethyl ether, acetonitrile, isopropyl alcohol, ethyl acetate. Each investigated its own, then varying combinations v/v ratios with ethanol. combination used investigate limit detection, lower quantitation, sensitivity, linearity previously studied antioxidants butylated hydroxytoluene, sesamol, rosemary extract. found yield improved depending tested. After comparing all merit, it 50%–50% ethanol—acetonitrile ethanol—ethyl acetate top five tested, providing a more alternative systems.

Multistep Surface Electrode Mechanism Coupled with Preceding Chemical Reaction-Theoretical Analysis in Square-Wave Voltammetry

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...

Surface Catalytic Mechanism in Square-Wave Voltammetry

A pseudo-first-order catalytic mechanism in which both reactant and product of the redox reaction are strongly immobilized on the electrode surface is theoretically analyzed under conditions of square-wave voltammetry (SWV). A mathematical procedure is developed for diffusionless conditions. The relationships between the properties of the voltammetric response and both the kinetic parameters of...

Determination of clopidogrel using square wave voltammetry

The determination of clopidogrel, an antiplatelet agent, was performed at a gold electrode in pH 3.7 acetate buffer using cyclic voltammetry (CV) and square wave voltammetry (SWV). Each voltammogram was characterized by the well defined peak at approximately 1.0 V. The current of anodic stripping peak exhibited a linear dependence on the clopidogrel concentration in the range from 317.89 to 935...
