Abstract:
Nitrosamines are a type of emerging disinfection by-products (DBPs), which are mainly formed during the reaction of disinfectants (especially chloramines) with precursors in source waters. The nitrosamine precursors have a wide range of sources and complex types, which has been one of the frontiers and hotspots in the water research filed of disinfection by-products at home and abroad. The occurrence, main sources and characterization methods of nitrosamine precursors were summarized, and the polarity rapid assessment method (PRAM) was introduced in details. The PRAM is a more efficient and rapid method for fractionalizing the bulk organic matter in water according to their polarity and electrical property than the classical resin fractionation method. The basic structure of nitrosamine precursors could be obtained utilizing PRAM as well as their removal mechanism by various water treatment technologies.
