Abstract: Iodinated disinfection byproducts (I-DBPs) are toxic drinking water contaminants formed when iodide-containing water undergoes conventional disinfection. Iodination of natural organic matter (NOM) initiates I-DBP formation and controls I-DBP formation potential. The proposed research will quantify NOM iodination reaction rates under simulated water treatment conditions using absorbable organic halogen (AOX) analysis. Solution conditions, including pH, [iodide], [chloride], and disinfectant dose, will be varied systematically in time-course experiments to reveal the factors controlling I-DBP formation. NOM iodination rate constants will allow computational modeling of specific conditions and integration with existing DBP research to help water treatment operators reduce public exposure to I-DBPs.
