Mecanisme dʹaction des radicaux OH√ sur les acides glycolique, glyoxylique, acetique et oxalique en solution aqueuse: Incidence sur la consammation de peroxyde dʹhydrogene dans les systemes H2O2/UV et O3/H2O2Mechanism of the reaction between hydroxyl radi

The aim of this work is to study the mechanism of the reaction of hydroxyl radicals with simple aliphatic acids (acetic, glycolic, glyoxylic and oxalic acids; see Table 1) in aqueous solution. The decomposition of organic acids by hydroxyl radicals has been studied using the photolysis of hydrogen peroxide and the ozone/hydrogen peroxide system.
