| Summary: | Monochloramine (MCA) is widely being used as a residual disinfectant in water distribution system
as it is more stable than chlorine and lessens the formation of disinfection by-products (DBPs). In
research, MCA are typically prepared right before each experiment as it decays significantly
overtime. However, the lack of standardized method for preparing MCA poses potential
consequences on their downstream applications. Several preparation protocols were chosen from
relevant journals and the performance of MCA produced were analysed. Various types of
degradation kinetics associated with MCA were examined and the abiotic and biotic factors were
also discussed. Finally, we studied the killing efficacies of MCA prepared to highlight the need of
having a standardised preparation protocol. |
