Reduced iron may account for the loss of chloramine disinfectants in water distribution systems. Experiments showed that a rate limiting direct reaction between monochloramine and ferrous iron resulted in the formation of an amidogen radical. Researchers determined that an autocatalytic reaction mechanism with ferric oxide precipitate accelerated the overall reduction of monochloramine. Radical scavenging accounted for the variability in the system stoichiometry. Complicated reactions between monochloramine and ferrous iron that result in the formation of amidogen radicals may lead to additional disinfectant loss and the formation of hazardous products. 20 refs.
