Complexation with ferrous ions accelerate the decay of N,N-dichloramines in corroded iron drinking water pipes

Key Points

• Decay of N,N-dichloramines is significantly accelerated by ferrous ions in corroded iron pipes.
• The presence of ferrous ions increases the breakdown rate of these compounds by up to 40% over various time intervals.
• Observational analysis of corroded iron water pipe samples reveals critical interactions with ferrous ions and dichloramines.
• These findings highlight that corrosion can significantly alter drinking water quality, which may impact public health.
