Precursors and Control of Halogenated Acetonitriles

Haloacetonitriles (HANs) are a class of nitrogenous disinfection byproducts that can form during disinfection of water with chlorine or monochloramine. This project is critical for advancing our understanding of the formation of HANs in water systems. By investigating the formation behavior and control of HAN formation across various water sources, the research offers unique comprehensive and systematic insights. The project's exploration of various chlor(am)ine formation potentials and treatment strategies enable broad and applicable conclusions. For example, it identifies model compound precursor types as well as conditions that maximize HAN formation while considering its degradation in differing water sources using chlor(am)ine disinfection, thus highlighting key factors influencing HAN formation behavior. Furthermore, the project outlines effective treatment strategies and disinfection approaches aimed at minimizing HAN formation. Published in 2026.
