Determination of Aconitic Acid by Square-Wave Voltammetry

Aconitic acid is three-carboxy unsaturated organic acid commonly found in many plants. A square-wave voltammetric method on mercury drop electrode has been developed for quantitative determination of aconitic acid in aqueous solution. The SW voltammetric outputs of its signal is a function on the type as well as the pH of the supporting electrolyte. The optimization of experimental parameters for quantitative determination of aconitic acid was achieved. The quantitative determination of aconitic acid was carried out in 0.1 mol/L HCl as a supporting electrolyte. The effect of interferences is studied. The detection limit of aconitic acid is about 0.18 μg/mL

Square-Wave Voltammetric Method for Determination of Fumaric and Maleic Acid—Determination of Fumaric Acid in Wine

A square-wave voltammetric method for determination of fumaric and maleic acid is developed. Both acids undergo totally irreversible redox reaction in neutral and acid media. The square-wave voltammetric response of the investigated acids is sensitive to pH, concentration of acids, type of the supporting electrolyte, as well as of the exciting signal parameters, such as frequency, amplitude and scan increment. All the experimental conditions as well as the instrumental parameters for quantitative determination of both acids were optimized. The detection limits of 116 mg/L for fumaric acid, and 230 mg/L for maleic acid are estimated. The proposed method enables simultaneous determination of fumaric and maleic acid. The method is applied for determination of fumaric acid in 10 kinds of Macedonian wines

An electrpochemical method for single and simultaneous determination of geometric isomers citraconic and mesaconic acid

The electrochemical behaviour of the isomer couple citraconic-mesaconic acid was studied in aqueous solutins by using square-wave and cyclic voltammetry in order to develop a method for their single and simultaneous quantification
