Significant quantities of largely unidentified byproducts are known to be produced from the reactions of ozone and natural organic matter (NOM) during preoxidation treatment of drinking water. The elucidation of the nature and identity of these ozonation byproducts is hindered by two complicating factors. The first is the inherent aqueous solubility of many of these compounds, which renders their efficient extraction from water difficult to achieve. Second is the lack of established identity of specific potential byproducts, which complicates targeted analytical approaches. To overcome these challenges, we have approached the task of byproduct identification by methods involving aqueous functional group-specific derivatization reactions. Aqueous functional group-specific derivatizations are described for carbonyls (multifunctional aldehydes and ketones) and epoxides. These procedures enhance the extractability of the analytes and provide an analytical "flag" for the specific compound classes. Derivatized compounds are extracted by solid phase extraction (SPE) and, in some cases after further derivatization, analyzed by gas chromatography-mass spectrometry (GC-MS).
