Abstract
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.
