Abstract

Polydiallyldimethyl ammonium chloride (polyDADMAC) is the most commonly used polymer at drinking water treatment plants and has the potential to form nitrosamines, like N-nitrosodimethylamine (NDMA), if free polymer is present during the disinfection process. The composition of polyDADMAC solutions used at the industrial scale is not well understood and is difficult to analyze. This study used 1H and 13C nuclear magnetic resonance (NMR) to analyze the polymer solution composition. Both 1H and 13C NMR are powerful tools that allow study of trace impurities in the solution, structural information such as chain length, and reaction mechanisms. The information garnered through 1H and 13C NMR can be used to mitigate NDMA formation at drinking water treatment plants.
