Abstract:
In this paper are presented the obtained results from studies maded through cyclic voltammetry, on platinum electrode, about electrochemical regeneration process of KMnO4 with aim to use it in chemical oxidation of quinoxaline and generation of pyrazine-2,3-dicarboxylic acid. It was investigated the effect of the support electrolyte concentration (KOH), concentration of K2MnO4, quinoxaline concentration and temperature. Anodic regeneration process of the Mn7+ is favored by increase of KOH concentration, temperature, Mn6+ concentration and quinoxaline concentration.
Keywords:
