✦ Synopsis

Abstract

The electrochemical oxidation of 3,4‐dihydroxycinnamic acid, caffeic acid, leads to a stable electroactive poly(caffeic acid) thin film containing quinone moiety on a preactivated glassy polymeric carbon electrode. The properties of the deposited films as well as the stability study under different experimental conditions were investigated. Taking advantage of the electrochemical behavior, an analytical method based on differential pulse voltammetry for determination of caffeic acid in red wine was proposed.

The stoichiometry of the formation of hydrogen peroxide from ascorbic acid in a model wine system has been examined by square-wave voltammetry (SWV) on a hanging mercury drop electrode. Both ascorbic acid and hydrogen peroxide could be determined in the same test sample by first employing an anodic
