Ozonation by-products of glucose in water


, : Ozonation by-products of glucose in water. Environmental Technology 16(11): 1035-1048

The aim of this work was to characterize and to quantify ozonation by-products of glucose in ultra pure water ((Glucose)-o = 5 mmol l-1; initial pH: apprxeq 6, final pH: apprxeq 3). HPLC and GC analyses showed that ozonation of glucose yields mainly gluconic acid (0.6 - 0.7 mole / 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 with six carbon atoms (hexosuloses, glucuronic and glucaric acids) and with less carbon atoms (acids and aldehydes).
