The overall objective of this study was to elucidate the transformation of representative QNOs,such as CDX, desoxyCDX, and ODX by reaction with free and combined chlorine under typicalwater disinfection conditions. Kinetics of these reactions were evaluated along withidentification of intermediates and oxidation byproducts. Structurally related compounds wereused to facilitate identification of reactive functional groups and further evaluate reactionmechanisms and pathways. In addition, the impacts of changing water quality parameters suchas pH and natural organic matter (NOM) concentrations were also assessed. Chemicals and solution preparation, experimental setup, and analytical analysis of QNOs and oxidation products in batch experiments are discussed. Includes 23 references, table, figures.
