| Abstract | The aim of this work was to characterize and to quantify ozonation by-products of glucose in ultrapure water ([Glucose](o) = 5 mmol 1(-1); initial pH : pH approximate to 6, final pH : approximate to 3). HPLC and GC analyses showed that ozonation of glucose yields mainly gluconic acid (0.6 - 0.7 mole I mole of glucose eliminated) and formic acid (0.2 - 0.25 mole / mole of glucose eliminated) at the beginning of the reaction. Glycolic acid, formaldehyde and peroxides were also formed for low ozone dosages. GC/MS analyses carried out on extracts from ozonated solutions of glucose and gluconic acid (90-95% removal of the initial organic compound) allowed the identification of several by-products wih six carbon atoms (hexosuloses, glucuronic and glucaric acids) and with less carbon atoms (acids and aldehydes). |
