Sorption and desorption of N-nitrosodimethylamine precursors bearing N, N-dimethylhydrazine moiety to solid-phase extraction media to aid their isolation and identification from environmental waters

Key Points

• Detecting trace-level precursors reduces the risk of NDMA formation in treated drinking water.
• Solid-phase extraction was utilized to isolate and identify ozone-reactive NDMA precursors from water samples.
• The study emphasizes the importance of monitoring carcinogenic disinfection byproducts in environmental waters.
• These insights support improved water treatment protocols by minimizing the presence of harmful precursors.
